Torque Practice

The easiest way to open a heavy door  is by applying the force

• Near the hinges
• In the middle of the door
• At the edge of the door far from the hinges
• At the top of the door

What is the Unit for Torque

• Nm
• N
• W
• J

Torque is the product of a force exerted on an object times the lever arm.

• True 
• False

Does a bridge anchored resting on two pillars have any torque?

• No, it isn't moving
• Yes, but it is at equilibrium
• Yes, but it will soon break because of the torque
• No, Bridges can't have torque

When an object is experiencing a net torque

• it is in dynamic equilibrium.
• it is in static equilibrium.
• it is rotating.
• it is translating.

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?

•  133.3 N
• 66.7 N
• 13.3 Nm

A state of equilibrium is also seen below. Each of the cars weighs the same 9800 N. Despite the fact that there is only one car on the left-hand side that is 9 m from the fulcrum, the torques balance because, the cars on the right-hand side, are (a)   meters from the fulcrum.

What direction is the torque acting with respect to post A?

• clockwise
• Counter clockwise
• Neither Direction
• Depends on the mass of the diver
