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

4. In order to determine the mass moment of inertia of a 4-foot
diameter flywheel, the flywheel is tested\twice with different
deadweight. In the first test a weight of 20 lb is attached by
cord and observed to fall 10 ft in 4.6 seconds. In the second
test a weight of 40 lb falls 10 ft in 3.1 seconds. Assuming that
the torque due to bearing friction is constant, determine mass
moment of inertia of the flywheel. Your solution must include
W
supporting FBDS.
