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

Problem 7: A 2 kg mass is hung from the end of a helical spring and is set
vibrating vertically. The mass makes 100 complete oscillations in 55 s.
Determine the stiffness of the spring. Also calculate the maximum amplitude of
