Question

I need help with Part B and C please.

Part A. If F3=0 and F1=12N, what does the magnitude of F? 2 have to be for there to be rotational equilibrium?

Answer numerically in newtons to two significant figures.

N

Part B

If the L-shaped rod has a moment of inertia I=9kgm2, F1=12N, F2=27N, and again F3=0, how long a time t would it take for the object to move through 45? ( ?/4 radians)?

Assume that as the object starts to move, each force moves with the object so as to retain its initial angle relative to the object.

Express the time in seconds to two significant figures.

Part C

Now consider the situation in which F1=12N and F2=0, but now a force with nonzero magnitude F3 is acting on the rod. What does F3have to be to obtain equilibrium?

Give a numerical answer, without trigonometric functions, in newtons, to two significant figures.
