Q2: Student A pulls on a wrench with 10 N a distance 5 cm from a bolt. Student B pulls on a wrench with 5 N a distance of 12 cm from a bolt. Which student applied a greater torque? (Both students applied the force perpendicular to the wrench handle.)

A. student A

B. Student B

C. Neither, they apply the same torque

D. not enough information

Q3: true of false: when computing the torque on an object, you must select an axis about which you compute the torque?

**bobpursley**, Wednesday, May 9, 2012 at 11:31amIf an object is at rest and is in a state of equilibrium, then we would say that the object is at "static equilibrium." "Static" means stationary or at rest.

I will be happy to critique your thinking on the remainng three.
