Concept explainers

Free Damped Vibrations
Free vibration is a type of vibration in which the external force is removed after giving the initial displacement to a body/system. In other words, in this type of vibration, force is applied at the initial displacement of the system, and after the init…
Question

Given a SDOF of spring-mass-coulomb damping, with mas of 0.1kg, stiffness of 10N s/m and a damping force of 0.1N is excited by a harmonic force of 1N amplitude at 1hz. Assuming steady-state condition, calculate the amplitude of vibrationn of the mass. How long the vibration will continu if the excitation is removed?
