Question

Torque is a twisting force. If the required torque applied on a 3 ft wrench is 45 ft·lb, what is the force that must be applied?

A) 135 lbs

B) 15 lbs

C) 135 ft·lbs

D) 15 rpm

Answer 1

15 lbs

Step-by-step explanation:

assuming you push from the end of the wrench (3ft)

torque = force(distance)

force = torque/distance

(45 ft·lb)/(3 ft)= 15 lbs
