A.) Calculate the moment of inertia I about
the pivot point.
Answer in units of kg · m2.

B.) The “torque” equation of motion forsimple k = kappa
harmonic motion is of the form τ = -kθ
When the rod is displaced by a small angle
from the horizontal and released, calculate
kappa. Assume θ is so small that the small angle
approximation may be used.
Answer in units of N · m.

C.) Calculate the angular velocity of the resulting
simple harmonic motion.
Answer in units of rad/s.
