The only time we ever cut a tree, we were shocked at how far it "jumped" with the final cut. The base of the trunk flew at least 12-15 feet, coming -way- too close to the truck supplying the tension. That pulley allowing the truck to supply tension from a different direction is nothing short of brilliant. If only youtube had been available in the 70s, we too could have been smart.

We use nothing but the best high tension steel in our safety pins.

Yeah, I saw something that suggested this was filmed in July, so you'd think there was more information. All the news I can find on it, just report about the "viral video", with no results on when and where for sure. You'd think that the company itself, or people there that day, would have seen it gone viral and put info out by now... though unless it was the company itself, it'd be harder to vet.

I'd wager the driver was okay in the cage, might have broke a bone or two, but otherwise was okay. The guy in yellow on the right would be the bigger concern, as he was buried. Near the very end you see somebody in black making a run across the far right as the last section collapses.

The crazy thing is, the shelf was barely hit. You probably hit it harder when putting pallets up. It must have been the perfect combo of angle and velocity, then add to that the tension on the legs given the way it was stacked and voila, disaster.

Meh, I buy it. He has to work within the limits of the tensioner, and how to get the velocity across the head reasonable and consistent seems like a hard problem to solve. I think there's probably more going on than just hooking some reel-to-reels up to a mixer, and it would be very interesting to know how he does it. Neat, though.

Could be he's just getting clicks and pops from some of the recorders and feeding that into an electronic drum trigger module.

Surely the solution should rather be to fix the real problem of unequal opportunity in primary education?

Even given disagreement on this, surely the left(you?) can acknowledge that reasonable good minded people could disagree? Surely it's an over-reaction to call people racist for believing that choosing students based upon performance and not race is a good thing? One has to acknowledge that the counter example, of using race before merit as a selection criteria is in fact the very definition of racism?

More importantly to the Democratic party though, allow me to gift them moral justice and rightness on the issue. Even given that, practicality dictates that spending many years with a policies that choose certain people over more qualified others based upon race will create tensions. If you made that policy against say whites, or males, they might develop resentment. One might predict that they may even vote against those imposing that policy, arguably even willingly voting for a kind of racist orange haired loud mouth that they hope will end the policy discriminating against them based upon their race.

You might even argue it's starting to happen already...

Really? WE sponsored a VIOLENT coup? So you take the purely Russian viewpoint.
Wiki-
After the breakup of the Soviet Union, Ukraine endured years of corruption, mismanagement, lack of economic growth, currency devaluation, and problems in securing funding from public markets.[38][39] Successive Ukrainian governments in the 2000s sought a closer relationship with the European Union (EU).[40][41] One of the measures meant to achieve this was an association agreement with the European Union, which would have provided Ukraine with funds in return for liberalising reforms. President Yanukovych announced his intention to sign the agreement, but ultimately refused to do so at the last minute. This sparked a wave of protests called the "Euromaidan" movement. During these protests Yanukovych signed a treaty and multibillion-dollar loan with Russia. The Ukrainian security forces cracked down on the protesters, further inflaming the situation and resulting in a series of violent clashes in the streets of Kiev. As tensions rose, Yanukovych fled to Russia and did not return.[44]

Russia refused to recognize the new interim government, calling the overthrow of Yanukovych a coup d'état, and began a military intervention in Ukraine. The newly appointed interim government of Ukraine signed the EU association agreement and agreed to reform the country's judiciary and political systems, as well as its financial and economic policies. The International Monetary Fund pledged more than $18 billion in loans contingent on Ukraine's adopting those reforms. The revolution was followed by pro-Russian unrest in some south-eastern regions, a standoff with Russia regarding the annexation of Crimea and Sevastopol, and a war between the Ukrainian government and Russia-backed separatists in the Donbass.



The thing to remember about Crimea is it WASN'T PART OF RUSSIA, so no it didn't hold Russia's only black sea port not ice blocked in winter, it held a Ukrainian port Russia LEASED for use by it's black sea fleet from the Ukraine.
It's utter bullshit that Russia found a democratic way to invade and annex Crimea, they militarily invaded, seized and dissolved the democratically elected government by force, created and installed a new pro Russian sham government, then IT signed fake illegal treaties with Russia in violation of international laws and multiple binding treaties.
https://en.m.wikipedia.org/wiki/Annexation_of_Crimea_by_the_Russian_Federation

Russian masked troops invade and occupy key Crimean locations, including airports and military bases, following Putin's orders.[2][3]
The head of Ukrainian Navy, Admiral Berezovsky, defects, followed later by half of the Ukrainian military stationed in the region.[4][5][6]
Russian forces seize the Supreme Council (Crimean parliament). The Council of Ministers of Crimea is dissolved and a new pro-Russian Prime Minister installed.[7][8]
The new Supreme Council declares the Republic of Crimea to be an independent, self-governing entity, then holds a referendum on the status of Crimea on 16 March, which results in a majority vote to join the Russian Federation.[9]
Treaty signed between the Republic of Crimea and the Russian Federation at the Kremlin on 18 March to formally initiate Crimea's accession to the Russian Federation.[10]
The Ukrainian Armed Forces are evicted from their bases on 19 March by Crimean protesters and Russian troops. Ukraine subsequently announces the withdrawal of its forces from Crimea.[11]
Russia suspended from G8.[12]
International sanctions introduced on Russia.

You sound distinctly Soviet or ridiculously ignorant in your misrepresentation of the situation. They militarily attacked, invaded, and seized their neighbor, so not a bit restrained, they were not invited in by the government and welcomed....or would you insist they are also exceptionally restrained for not attacking and retaking Anchorage Alaska, their only non winter ice bound port in North America, a port clearly more strategically important than Sebastopol and just as Russian?

Why is the instrument used in the mouth?

It looks to me like you vary the pitch by changing the tension on the string.

Cool song though

I'm a structural enginerd...I have years of prestressed concrete experience. I agree with this video. Post tension failure hit my brain as soon as I saw the video. Sudden loss of strength. PT concrete without PT = unreinforced concrete = sudden loss of strength = brittle failure. However, the PT cable could have been made of subpar materials. I once broke a #6 rebar with one hand in front of the Owner, inspector, and Contractor! Regardless, the PT rod was likely at yield when it was being tightened. As soon as it reached Fu...boom. What goes through the brains of the guys tightening a PT rod and notices the cable doesn't take load!

Your video, Post Tension Failure Florida Bridge Collapse Eng. Explained, has made it into the Top 15 New Videos listing. Congratulations on your achievement. For your contribution you have been awarded 1 Power Point.

Like accidentally pushing something over the edge of the platform? Or not securing the cargo and have it shaken overboard by vibrations during the move? Or having the top of the ladder come loose from the railing? Or the railing itself?

Nah, it's fine, just fine.

But I am curious. I have had to move a few times, and I have helped friends move a few times as well, for a total of maybe ~15 times. And the light stuff they put on the platform in this video has never bothered me. Granted, it has never been higher than 12th floor for me, but hauling bulky, "low-weight" stuff downstairs -- no issues. It's the heavy stuff through narrow stairwells that's been a pain in the behind. Yet they don't seem to have a net or tension belts attached to it, so do they use it for bulkier/heavy stuff as well?

$40-$60 million more in undisclosed payments to Manafort surfaced last week....but Trump has nothing to do with the Trump for president campaign, does he?....and did I say collusion, or even Trump? Nope, but a guilty conscience hears accusations that never happened.
The Russians today are doing exactly what you do, pretending to be right wing nutjobs on left leaning sites, and lefty snowflakes on right leaning sites, pushing the narrative to all that the other guy is a total nut by making ridiculous, ignorant claims like you do. If you aren't being paid by Putin, you're working for him for free.

Jesus fucking Christ, Bob. Can you be more deluded and ignorant? Once again, your Russian text book of American history is 100% ass backwards.

Southern strategy: In American politics, the southern strategy was a Republican Party electoral strategy to increase political support among white voters in the South by appealing to racism against African Americans.[1][2][3] As the Civil Rights Movement and dismantling of Jim Crow laws in the 1950s and 1960s visibly deepened existing racial tensions in much of the Southern United States, Republican politicians such as presidential candidate Richard Nixon and Senator Barry Goldwater developed strategies that successfully contributed to the political realignment of many white, conservative voters in the South to the Republican Party that had traditionally supported the Democratic Party.[4] It also helped push the Republican Party much more to the right.[4]
Not Nixon courting the black vote.

Troll: Internet slang, a troll (/ˈtroʊl/, /ˈtrɒl/) is a person who sows discord on the Internet by starting quarrels or upsetting people, by posting inflammatory,[1] extraneous, or off-topic messages in an online community (such as a newsgroup, forum, chat room, or blog) with the intent of provoking readers into an emotional response[2] or of otherwise disrupting normal, on-topic discussion,[3] often for the troll's amusement.
Definitely you, Dimitri. It's almost time to have lucky investigate your ip address to see if you're in Kiev or Moscow.

Yeah. More than once I think. It was a long ass time ago, but I remember the end involves you leaving the mansion, amid happy-ish music and a bright sunny day, and being picked up by your driver who ends up being this undead skeleton dude or something.

The game I'm really enjoying right now is Prey (2017). OMG so good. I saw some let's plays of it and initially it felt underwhelming, but the game is so immersive and non-linear, with a great story and evolving game world... It's not so much a horror game, but it has tension and some jump-scares here and there. I feel like it's got some gameplay similarities to Alone in the Dark 1, oddly enough, despite being completely and entirely different.

I've never seen anything that beats the car chases in Ronin.

This is good, but suffers too much from the current culture of many fast cuts rather than really setting the scene and letting us join the action. I also think the cutting is a little too predictable, partly because they basically re-use three different shots over and over with only occasional drops to different POVs. It also feels a little too much like "look what stunts I can do" rather than an actual life (in prison) or freedom car chase which drains much of the tension from the scene.

It's not a joke. It's hypocritical, but quite serious. Because they focus on the fact that he appears to be under Putin's control does not mean they ignore his myriad of other faults....proven by the near weekly protests against his policies.

Jesus Christ...they aren't upset the he wants to normalize relations with Russia, they're upset that he seems to be a Russian agent, as do many of his cabinet, and they fear he'll do things to benefit them instead of actually working for America.
People are upset at his people illegally, treasonously 'talking' to the Russians about removing sanctions and other subversions of established federal policy and law before they were in power and bold faced lying about it under oath and publicly uncountable times, not for having normal or legal diplomatic discussions. They won't accept it when the next president takes control on Nov. 8 and reverses their policies before taking office.

The emails themselves had no new information, it was the implication that they did, and that the investigation was still actively under way that hurt her. The media absolutely covered that, what are they talking about?

It's not about escalating tensions between the U.S. and Russia, it's about abandoning normal policy and giving Russia what they want, carte Blanche to expand and reform the USSR.

I guess they forgot that Russia is building it's military on it's borders and expanding it's territories into our allies countries, and that's why NATO moved, to protect our allies, not to provoke poor little innocent Russia. Just fucking duh.

They aren't necessarily shills for Russia, they are, however, being shills for Trump, and Chomsky now seems to be moving in that direction based on this video. This is the most idiotic thing I've heard from Chomsky, as it completely ignores reality and reason to lambast people for being worried their president may be (as all evidence indicates he is) an agent for one of our worst enemies.

Sorry Chomsky, big fail.

I think one of the coolest things of my childhood was tapping one of the high-tension lines holding a telephone pole in place and discovering where he found the sound for the blasters.
