Question

In the picture below, a 10 kg bar 1.1 m long is set up to rotate about its center (the dark circle). Each arrow represents a force that is being applied to the bar. FA = 42N, FB = 45 N, FC = 21 N, & FD = 14 N. FB and FC are applied halfway between the center and the end while FA and FD are applied right at the ends. Using the center as the pivot point, answer the following questions.



a.) Determine the net torque on the bar.
____ m·N

b.) Determine the moment of inertia of the bar.
____ kg·m2

c.) Determine the angular acceleration of the bar.
____ rad/s2
