And can someone tell me how ft lbs translates to human strength? Or does it not work that way because torqueing something to 89 lbs feels a fuck ton more heavy than moving 89lbs

Torque is just force but in a circlular or curving direction, so it's mainly used when rotating bolts and other things.

Moving something 89 pounds isn't really comparable to torqueing something 89 pounds. When you're moving something, you're just fighting against the friction. So if that 89 pound thing had wheels, it would be more like 9 pounds, or if it didn't, maybe 34 pounds after friction. When they say 89 pounds of torque they mean a full 89 pounds, all of it applied to the object. It would be more comparable to lifting up something that's 89 pounds off the ground

Well, it depends on the length and gear ratio of the wrench you're using.

If you have a 1:1 wrench (god forbid) and it's 1 foot long, then 89 ft lbs feels like 89 lbs. If you take the same wrench and stick a 1 ft steel rod on the end of it, then 89 ft lbs feels like 49.5 lbs. switch out the wrench for a 1:3 one and it feels like 16.5 lbs.

To add to >>8153420, remember also that you increase torque applied by the same force by using a longer wrench - that's why it's ft lbs and not lbs. So trying to compare what you "feel" vs another activity is only relevant to the force you are putting in, not the torque at the other end.

Torque is the object being pushed into itself in order to add up to that amount of force, so you're compressing molecules to all push back on each other at 89lbs.

Your wanting the nut to be pushing on the threads harder than the object being held will push the nut, so the difference doesn't make the nut come loose, right?

I sincerely hope you are trolling.

Okay, I have a 7" box wrench. What does that mean torque wise.

Now, what kind of multiplier is it with torque wrenches? How does that work?

It means that to apply 89 ft lbs of torque you need to apply a perpendicular force of around 127 lbs to the end of your wrench.

A torque wrench takes advantage of special gears to make it as if you were turning a very very long wrench. There's a little meter on it that tells you the total torque you're applying.

Wait really?
I thought torque wrenches just had a setting you could set it to so you apply exactly that much torque without going over.

look up "moments" in physics, OP
