A small connecting rod of mass 1.5 kg is suspended in a horizontal plane by two wires 1.25 m long. The wires are attached to the rod at points 120 mm on either side of the centre of gravity. If the rod makes 20 oscillations in 40 seconds, find the mass moment of inertia of the rod about a vertical axis through the centre of gravity.

Simple Harmonic Motion topics include: Simple harmonic motion and its equations, velocity and acceleration of particle, simple and compound pendulum, centre of precision, bifilar and trifilar suspension. Simple harmonic motion (SHM) is a type of periodic motion that occurs when an object experiences a restoring force. The magnitude of this force is directly proportional to the object's distance from an equilibrium position, and it acts towards that position.  SHM is characterized by a restoring force that is proportional to the object's displacement. The motion of the object is described by... Show more
