RMS Titanic: Fascinating Engineering Facts

oritteropo says...

There were multiple factors involved, and in the case of the Titanic sinking it was possibly partly related to the water temperature and the properties of both the steel hull and the rivets, as well as the design and the careless operation of the vessel.

Before the wreck was found, much more was made of the design of the watertight bulkheads which only went up to E deck. This allowed any four to be compromised without sinking the vessel, but six were breached in the Titanic, so as the boat tilted more, water could flow over the top of the bulkheads.

More recently, since inspection of the wreck became possible, metallurgy has been blamed much more. The hole made by the iceberg was straight and at the bottom of steel panels, indicating rivet failure. Testing of the steel used in the construction also found quality issues there, impurities would have made it more brittle than intended.

The first video on the subject that came up was this one:

Sounds to me like the real flaw to these ships was the thickness of steel used on the sides of the ship.
All three were sunk in similar fashion. One single hit to the side of the ship.

Sarah Palin after the teleprompter freezes

newtboy says...

You are partially correct, I listed the rank of a top submarine officer incorrectly, but not his position, I'm not in the Navy. He was Executive Officer of the first nuclear sub, but only First Lieutenant of the diesel. EDIT: He "qualified for command" of the nuclear sub...probably why I thought "commander" but properly should have said "was in command". Shortly after being assigned to lead the nuclear sub trials, after helping design and build it, he led the American shut down of the Chalk River reactor, lest you continue to insinuate he was an 'armchair warrior' that never held command.
(record below)

◾17? DEC 1948 - 01 FEB 1951 -- Duty aboard USS Pomfret (SS-391) Billets Held: Communications Officer, Electronics Officer, Sonar Officer, Gunnery Officer, First Lieutenant, Electrical Officer, Supply Officer Qualifications: 4 Feb 1950 Qualified in Submarine


◾05 JUNE 1949 -- Promoted to Lieutenant (j.g.)


◾01 FEB 1951 - 10 NOV 1951 -- Duty with Shipbuilding and Naval Inspector of Ordnance, Groton, CT as prospective Engineering Officer of the USS K-1 during precommissioning fitting out of the submarine.


◾10 NOV 1951 - 16 OCT 1952 -- Duty aboard USS K-1(SSK-1) Billets Held: Executive Officer, Engineering Officer, Operations Officer, Gunnery Officer, Electronics Repair Officer Qualifications: Qualified for Command of Submarine Remarks: Submarine was new construction, first vessel of its class


◾01 JUNE 1952 -- Promoted to Lieutenant


◾16 OCT 1952 - 08 OCT 1953 -- Duty with US Atomic Energy Commission (Division of Reactor Development, Schenectady Operations Office) From 3 NOV 1952 to 1 MAR 1953 he served on temporary duty with Naval Reactors Branch, US Atomic Energy Commission, Washington, D.C. "assisting in the design and development of nuclear propulsion plants for naval vessels." From 1 MAR 1953 to 8 OCT 1953 he was under instruction to become an engineering officer for a nuclear power plant. He also assisted in setting up on-the-job training for the enlisted men being instructed in nuclear propulsion for the USS Seawolf (SSN575).


On December 12, 1952, an accident with the experimental NRX reactor at Atomic Energy of Canada's Chalk River Laboratories caused a partial meltdown. The resulting explosion caused millions of liters of radioactive water to flood the reactor building's basement, and the reactor's core was no longer usable.[7] Carter was ordered to Chalk River, joining other American and Canadian service personnel. He was the officer in charge of the U.S. team assisting in the shutdown of the Chalk River Nuclear Reactor.[8] The painstaking process required each team member, including Carter, to don protective gear, and be lowered individually into the reactor to disassemble it for minutes at a time. During and after his presidency, Carter indicated that his experience at Chalk River shaped his views on nuclear power and nuclear weapons, including his decision not to pursue completion of the neutron bomb.[9]

Just to correct a few fantasies here...Carter completed qualification to run a diesel sub, he was never the commander of a nuclear sub. He was never the captain of any ship, apparently, except the ship of state, which he proceeded to drive onto the sandbar of malaise.

O God, thy sea is so great and my boat is so small…

SFOGuy says...

Part of the problem with hydrofoils is exactly what you're seeing---once the waves reach the point where the bottom of the vessel is slapping the water each time the waves crest underneath it, a lot of stress and acceleration becomes inevitable---and you're not foiling anymore.

That's why, for the most part, hydrofoils end up being restricted to operations where the bodies of water they are operating on are partly in the lee of something else or sheltered (Lake Como; the Hong Kong/Macau run; Norwegian fiord patrol craft; Baltic sea, etc...) in my recollection...

Reminds me to never ride in a ship without hydrofoils.

There's a Secret Vehicle on the Millennium Falcon!

MilkmanDan says...

I agree, but to play devil's advocate here are two counterpoints:

1) The YT-1300 was designed as a freighter, and the Millennium Falcon only became a capable warship after pretty extensive modification by Lando and Han Solo. So, perhaps some of those flaws can be justified with "not really intended to be a combat vessel" rationale.

2) Or even ignoring that, shielding seems to be established as being much more important than armor plating around wires and pipes in the Star Wars universe. TIEs (at least the lower models) have no shielding whatsoever, and the only thing that separates them from just being pure cannon fodder is size, agility, and numbers.

But even in medium fighters that DO have shields, it seems like they at best protect against a very low number of glancing hits -- we see X and Y wings with shields go down after 1-2 hits a LOT in the movies. In that scenario, I guess there isn't a whole lot of need to slow yourself down with heavy armor plating that might let you survive another hit if you are lucky. Kinda like how modern police officers and soldiers don't wear heavy steel plate armor; they either wear kevlar (think "shields") or nothing but clothing/uniform.

So, maybe the larger ships in Star Wars stock up on shields and aren't too fussed about physically covering up systems -- once the shields are down you're pretty much toast anyway.

I love the Millennium Falcon... one of the greatest spaceships in sci-fi. But watching it closely, it has some stupid design flaws... all that wiring and pipes and whatnot totally exposed.

Riders on the Storm

ghark says...

Had that once on a vessel I worked on, but it was side to side - and an engineer flew into an amazingly beautiful blond girl and landed on top of her with a tray of frozen fish. Was very romantic.

Man Locked In Hot Car To Prove Babies Are Weak

Sagemind says...

I'd like to see this video on a regular hot and sunny day.
It gets hot here. on a regular summer day we can easily get to 35ºC - 40ºC (95ºF - 104ºF) - inside a car, it will climb to 50ºC (122ºF) and hotter.

I've sat in a car with the windows rolled up (not even realizing), and after about four minutes, I was drenched in Sweat and burst a vessel in my nose, causing a nose bleed.

This guys example couldn't even have been on a very hot day - maybe a warm day - not a hot one though...

Goliath Grouper Attacks Diver, Steals His Fish and Spear Gun

possom says...

They are a delicacy.. very high end seafood fare and hard to find in restaurants. I caught a 75lb, a fraction of this size, and sold it for 100$. These fish are well regulated with normally only one allowed per vessel.

QI - Only Survivor of the Crimean War

CreamK says...

The only naval vessel to be captured and not returned back to British is in my hometown... It happened during the Crimean war, we built a simple wall and spread molten tar all over our beaches.. Pretty much impossible to get thru that mess.. It's still in there, the tar allthout it's slowly vanishing.. All the other coastal towns were ransacked but ours... We still have the boat but we'll give it back if shit hits the fan with out easter neighbor, who are spreading lies already that Finland wants to join Russia... Don't believe that nonsense, nothing could be further away from truth.

Big Budget Hollywood Movie About Noah's Ark with Russel Crow

Deano says...

It's all about the in play! (Subtle Ray Winstone reference).

I would love to have a laugh at this once it's on Netflix. Why does Anthony Hopkins always sound like he's phoning it in? Such an overrated actor.

And where's Ridley Scott? Thought he was married to Crowe?

I wonder if they'll go into the shipbuilding technology required to build a single super large vessel capable of surviving a world-wide flood?

BASE Jumper Almost Loses Foot, Handles it Well

worthwords says...

infection is a secondary concern, Your immediate danger is neurovascular compromise. If the foot doesn't have a blood supply then it's dead within hours. Often this involves manipulation and realignment at the scene since blood vessels can get kinked
