I exist onl because of Parias'
LEGENDARY GENEROSITY.

So the rear differential on my '89 Cherokee decided it didn't want to make it to 400,000 KM. Only 3,000 more to go Was just outside of town and doing about 100 KPH when I heard a loud KABANG! and thump thump thump thump as the jeep slowed to a hault. gently caress. Got it back home the next day and found a surprise in my diff.







The pinion gear is mostly gone, shredded into bits. Took out some of the ring gear, and part of the housing. It still had plenty of oil in it, I guess it was just over stressed from 397,000KM of abuse. Goodbye, Dana 35, you served me well.

Ouch, good thing it didnt lock up. I had the ring gear explode in my volvo 740's rear axle in a parking lot. Locked my tires right up, I could go forward and backwards about 2 feet before locking. I have some pics around here somewhere.

I dont know who's bike this was, but they managed to saw the chain clean through the derailleur. I wonder how long they pedaled, slowly grinding away at it?

For someone who daily drives a 10 speed, this took me entirely too long to rationalise what I was looking at.

It looks more like it just snapped, you wouldn't be able to shift into any higher gear and still have it rubbing against the chain. Hell, the only way I can see you sawing through would be if you had such a poorly adjusted derailleur that it was rubbing in the smallest gear, and that wouldn't break it that high up.

Well, how did it snap then? That's not exactly a high stress area. I was justifying it as either riding on the larger gear or chain flex. Other than that I've got absolutely nothing.

The chain was on the middle of the three larger sprockets, and the deraileur was bent in towards the frame. The bike would be unable to shift to the largest gear but could seat on the middle one while rubbing.

OVERWORKED COCK


Slippery Tilde

Requesting picture of the USAF truck that crashed into the nose of some high performance aircraft parked on the flight line.

I don't have a picture but I have a story. In 1988 I saw a mid 80's GM truck that looked like this can on the side of highway 4 in the bay area in California.



I saw the same CHP officer later and asked him what happened. He told me the guy used a tow strap to tie down a load in the bed. He never secured it after dropping off the load he threw the excess strap into the bed. It came partially loose and it got caught in the driveshaft. It fell down between the cab and bed and squeezed the frame rails together, it was still attached to both sides of the frame and "up and over" the bed. it crushed the bed and pulled the cab back and down into the bed.

Luckily nobody was injured.

Side impact from clipping a rock/stick? But that'd require some pretty unlucky trajectories to get past the pedals.

Micros theory would work as long as they never changed down a gear. (Which in a fairly level area isn't an unreasonable assumption.)

Given how poorly adjusted his derailleur obviously is if it's impossible to go to the 3rd cog, it's possible he couldn't change.

I had this happen to me....same axle as well. Didn't lock up, so I dragged myself home in 4x4 mode using the front axle, cringing as I heard the metal shards in the back scraping and popping and clanging.

N'awww, it's a cute little transformer.

I mean hell, my solid-state exciter isolation transformers are at least 40kVA with a high K-factor to boot. I don't consider a transformer "big" until you get over 10MVA. I am curious where he's going to get the 100-150kVA from.

Anyways, it's also kind of neat to see that people this British actually do exist. And he's going to hook it to 300A at 240V, wow. That's greater than 4/0 cable.

I used to work in white goods testing & we did highspeed video of drums failing at high speed, in an armoured underground bunker. They tend to be fine up until 11000-11500 rpm before they wobble. Then you have to go see how much of the video kit survived

Unfortunately I have no video to show.

post pictures youtubes links to a blogspot with embedded google video of horrible mechanical engineering failures

quote:

The now generally accepted explanation is that a miscalculation by Texaco regarding their location resulted in the drill puncturing the roof of the third level of the mine. This created an opening in the bottom of the lake, similar to removing the drain plug from a bathtub. The lake then drained into the hole, expanding the size of that hole as the soil and salt were washed into the mine by the rushing water, filling the enormous caverns left by the removal of salt over the years. The resultant whirlpool sucked in the drilling platform, eleven barges, many trees and 65 acres (260,000 m2) of the surrounding terrain.
