Question
Consider the simple pendulum: a ball hanging at the end of a string. Derive the expression for the period of this physical pendulum, taking into account the finite size
ball (i.e. the ball is not a point mass). Assume that the string is massless. Start with the expression for the period T'of a physical pendulum with small amplitude oscillati
T
= 2π
The moment of inertia of the ball about an axis through the center of the ball is
Here, I, is the moment of inertia about an axis through the pivot (fixed point at the top of the string, m is the mass of the ball, g is the Earth's gravitational constant of
acceleration, and h is the distance from the pivot at the top of the string to the center of mass of the ball.
Note, this pre-lab asks you to do some algebra, and may be a bit tricky.
