Force applied to lever arm to twist foot pound torque

[Tony Singh]

If i need 1000 foot pound torque of 1000 foot pounds twisted very easily
How long should the lever arm be and and how much force at the end of lever arm is required ?

you just calculate it T=force *distance. It depends on the lever arm and force that you have applied. Your equation should be like that 1000 foot pound=F*x , Now you have two unknown.Of course, you need more data to solve the question. Hope it is clear.

I once designed an eyebolt that needed to be tightened to 3000 ft-lbs. We took a 15 foot long pipe and welded a bracket to one end. Somebody brought in a 300 lb capacity spring scale designed for weighing deer and hooked it to the other end of the pipe. Three men on a rope pulled 200 lbs, and we had our 3000 ft-lbs.
