If an object has a net force of zero on it, and a net torque of zero on it, it must be in static equilibrium. 7) T or F If an object is in static equilibrium, it does not matter where the axis of rotation is located. The net torque is always zero. 8) T or F There are cases where an object traveling in a straight line can have a non-zero angular momentum. 9) T or F Like rotational kinetic energy, angular momentum can be zero or positive, but not negative. 10) T or F

An automobile engine can produce 200Nm of torque. Calculate the angular acceleration produced if 95.0 of this torque is applied to the drive shaft, axle, and rear wheels of a car, given the following information.
