In order to find the radius of gyration of a car, it is suspended with its axis vertical from three parallel wires 2.5 metres long. The wires are attached to the rim at points spaced 120° apart and at equal distances 250 mm from the axis. It is found that the wheel makes 50 torsional oscillations of small amplitude about its axis in 170 seconds. Find the radius of gyration of the wheel.

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
