"A bolt is to be tightened with a torque of 7.6 N · m. If you have a wrench that is 0.20 m long, what is the least amount of force you must exert in N?"

I thought torque was equal to length times force, but apparently force is not equal to torque divided by length... Help?

torque = force applied * length

7.6 = F * 0.2
force = 38 N

You are correct, torque = r * F if F is perpendicular to length, so F = T/r

Divide 7.6 N-m by 0.20 m. What makes you think that's wrong?
