Answer 1

Answer #1

Rotational kinetic energy = 0.5*I*w^2

w = 2*pi/T = 2*pi/0.02

w = 100*pi

I = moment of inertia of rod along x-axis

I = m*L^2/12 + m*R^2/4

I = 6*0.4^/12 + 6*0.06^2/4 = 0.0854

So,

KEr = 0.5*0.0854*(100*pi)^2 = 4214.32 J

In lecture we found that the center of mass of a rod with a non-uniform density profile (where the density changes linearly from one end to the other, doubling in density from one end to the next) was 5/9L when measured from the less-dense end. We also found that the rotational inertia around the less-dense end came out to be 7/18ML2. Use these facts and the parallel-axis theorem to find the rotational inertia of this rod around its center of...
