Torque Problems

If the torque required to loosen a nut on the wheel of a car has a magnitude of 60.0 N• m, what minimum perpendicular force must be exerted by a mechanic at the end of a 45.0 cm wrench to loosen the nut?

• .666 Nm

•  133.3 N

• 66.7 N

• 13.3 Nm

Find the magnitude of the torque produced by a 5.0 N force applied to a door at a perpendicular distance of 65 cm from the hinge.

• 75 Nm

• 3.25 Nm

• 6.3 Nm

• 8.75 Nm

A wrench is used to tighten a nut. A 15N perpendicular force is applied 50cm away from the axis of rotation, and moves a distance of 10 cm as it turns. What is the torque applied to the wrench?

• 7.5 Nm

• 1.5 Nm

• 750 Nm

• 150 Nm

What is the distance the masses on the right of the fulcrum need to be to balance with the two masses on the left?

• .65 m

• .56 m

• .79 m

• .39 m
