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.

when it is at A it has a speed of 10 ft/s. If the spring to which
it is attached has an unstretched length of 3 ft anda stiffness
of k = 10 lb/ft, determine the normal force on the collar
