(24.3.17) The torque about the center of mass is given in the statement of the problem as a restoring torque, therefore τ cm =−bθkˆ. (24.3.18) The z-component of the rotational equation of motion is −bθ=I cm d2θ dt2. (24.3.19) This is a simple harmonic oscillator equation with solution θ(t)=Acos(ω 0 t)+Bsin(ω 0
