Answer to Question #95344 in Civil and Environmental Engineering for Shamal

Question

Torsional Vibrations. Undamped torsional vibrations (rotations back and forth) of a wheel
attached to an elastic thin rod or wire are governed by the equation I0θ
00 +Kθ = 0, where θ is
the angle measured from the state of equilibrium. Solve this equation for K/I0 = 13.69sec−2
,
initial angle 30◦
(= 0.5235rad) and initial angular velocity 20◦
sec−2
(= 0.349rad · sec−1
).
