Question 1 Easy

A mechanic pulls on the end of a 0.25 m wrench with a 160 N force perpendicular to the handle. The wrench grips a rusted bolt, but the bolt does not turn.

Which of the following correctly describes the work done on the bolt by the wrench's torque?
A40 J40\ \text{J}, because work equals torque when both have units of newton-meters.
BPositive, because the mechanic exerts a large force on the wrench's handle.
CZero, because the wrench exerts no torque on a bolt that does not turn.
DZero, because the bolt does not rotate while the torque is exerted.

Topic 6.2: Torque and Work

Learning Objective: 6.2.A

Describe the work done on a rigid system by a given torque or collection of torques.

Essential Knowledge: 6.2.A.1

A torque can transfer energy into or out of an object or rigid system if the torque is exerted over an angular displacement.

Essential Knowledge: 6.2.A.2

The amount of work done on a rigid system by a torque is related to the magnitude of that torque and the angular displacement through which the rigid system rotates during the interval in which that torque is exerted. Relevant equation: W=τΔθW = \tau \Delta\theta

Essential Knowledge: 6.2.A.3

Work done on a rigid system by a given torque can be found from the area under the curve of a graph of torque as a function of angular position.
