That's one of the ones where you know what's going to happen but you watch it anyway.

LOL

He wasn’t trying to remove the bush, he was just testing his roll cage. Nothing wrong here.

What is torque anyway?

True. But it was even more entertaining than I expected.

Why wear a seatbelt? I’m less than 4 miles from home! Also, I’m not going that fast

Scenario: You are changing the half-shaft on a FWD automobile. There’s a large nut holding the front hub together. Something like 24 or 32 mm. You weigh 200 pounds. You put a 36-inch pipe over your breaker bar and you stand on the end of the bar. You don’t jump or bounce, you just stand there. You get your brother to put down his beer and his cigar and get up off the porch — it’s
his
car after all — and have him come over and photograph you with his iPhone 6. The picture will show a
moment
of torque being applied to that nut which, by the way, probably didn’t budge.
The bar is 3 feet long and you weigh 100 pounds. 3 ft x 100 lbs = 300 pound-feet of force —
torque
— applied to that nut in that relative instant.
The key idea here is that torque is measured in a
moment
or an
instant
. So when car manufacturers are talking up the amount of torque their car’s engine generates, it doesn’t mean much because torque is an instantaneous measurement and your car is constantly accelerating and decelerating and the amount of torque being applied is constantly changing.

I was being facetious.

shoulda left that engine in the chainsaw and just cut the bush down.

Sorry. Did I do a good job explaining it?

Should’a tethered it lower down, but then you’d just get wheelspin because no downwards pulling effect..

I have an iPhone 5S. But the rest is pretty accurate.

Those bushes are actually very stubborn. I tried doing the same thing with my F150, with 4WD and lockers, but it would just spin the tires. Quite embarrassing.

Dude, you should have used a Massey-Ferguson. True story: in central MS, there is a soil formation called Yazoo clay; nasty stuff, expands and becomes plastic when wet, shrinks and turns to concrete when dry. After a long dry spell, trying to dig up similar size shrub, got frustrated and decided to yank it out with trusty Isuzu pickup. Backed truck to within 2 feet of shrub. Hooked 12-foot braided nylon tow rope to truck and shrub, put truck in low gear, gunned engine. Two seconds later, truck was stalled, my internal organs were rearranged, tow rope was seriously stretched, shrub (and large chunk of surrounding clay) was against back bumper of truck, wife was collapsed on ground howling with laughter. Truck had moved rapidly to end of tow rope, rofope had stretched to its limit, truck stopped like it hit a battleship, shrub and clay flew out of ground and up against back bumper. No damage to truck (or house, luckily). Moral of the story: be careful, and before you try something like that, fasten seat belt/shoulder belt TIGHT.

I enjoyed reading you scenario.

Thank you. That’s my book report, actually. I trolled a couple of engineers a few weeks back about torque, did some homework of my own, and tried to put it into terms that a 7th grader could understand. No affront intended there, because I am in fact a 7th grade math teacher.
Thanks for the reply! (And my brother actually owns an iPhone 5...)

Thank you for teaching math.

You’re welcome, but no thanks necessary. There are days when I actually enjoy it.
