Concept explainers

Free undamped vibrations

Whenever an object/system displaces in either side of its equilibrium position with the help of an external/internal means, then the object/system moves regularly or randomly on both sides of its equilibrium position. This motion is called vibration. Generally, there are three types of vibration: longitudinal vibration, transverse vibration, and torsional vibration.

Question

A relatively thin disc with uniformly distributed mass is mounted on a
shaft which rotates at 1000 RPM. To conduct a test, two extra masses

and B introduce known unbalances of 2 kgmm and 4 kgmm,
respectively. Determine the angular location of the correction mass
measured from y-axis in the clockwise direction and the centrifugal force
that it needs to produce in order to balance the system.
