Sometimes, even with a wrench, one cannot loosen a nut that is frozen tightly to a bolt. It is often possible to loosen the nut by slipping one end of a long pipe over the wrench handle and pushing at the other end of the pipe. With the aide of the pipe, does the applied force produce a smaller torque, a greater torque, or the same torque on the nut? smaller torque O greater torque O same torque

A rigid body is rotating. Is it necessary that a net torque acts on the body?

The Achilles tendon inserts on the calcaneus (the heel bone) at a distance of 8 cm from the axis of the ankle joint. If the force generated by the muscles attached to the Achilles tendon is 3000 N, and the moment arm of this force about the ankle joint is 5 cm, what torque is created by these muscles about the ankle joint?  Hopefully it’s enough torque to move out of the way so the arrow doesn’t shoot through the tendon.

Pinky the cat sits on top of a pump handle that is 50 cm long. What is the torque generated by Pinky's weight of 30 N due to him sitting on top of the pump handle? 5 N-m O N-m 43 N-m 26 N-m 13 N-m 19 N-m
