A 20.0 cm wrench is used to generate a torque at a bolt. A force of 50 N is applied perpendicularly at the end of the wrench. The torque generated at the bolt is
A) 8.0 N·m.
B) 10 N·m.
C) 14 N·m.
D) 22 N·m.
E) 37 N·m.

Question

Quizplus · Accepted Answer

Torque is calculated using the formula torque = force x distance. Here, the force is 50 N and the distance (length of the wrench) is 20.0 cm = 0.2 m. Therefore, the torque is 50 N * 0.2 m = 10 N·m.
