1. What is the unit of torque?
Newton (N)
Joule (J)
Newton-meter (N·m)
Watt (W)
2. For an object to be in rotational equilibrium, the net torque acting on it must be:
Positive
Negative
Zero
Constant
3. Torque is the rotational equivalent of a .
4. The perpendicular distance from the pivot to the line of action of the force is called the arm.
5. A uniform rod of length 2.0 m is pivoted at its center. A 10 N mass is hung at one end. Where must a 20 N mass be hung to balance the rod?
6. Explain the conditions for static equilibrium.
7. Torque is a scalar quantity.
True
False
8. An object in static equilibrium must have zero net force and zero net torque acting on it.
True
False
Match the term on the left with its definition on the right.
9. Torque
a. The condition where an object is at rest and remains at rest.
10. Lever arm
b. The perpendicular distance from the axis of rotation to the line of action of the force.
11. Static equilibrium
c. A force that causes rotation.
12. A mechanic uses a wrench to loosen a lug nut. The wrench is 0.30 m long, and the mechanic applies a force of 150 N perpendicular to the wrench at its end. Calculate the torque applied to the lug nut.
