If the loading F(t) is a Heaviside step function (the sudden application of a constant load), the solution to the equation of motion is: where = k M {\displaystyle \omega ={\sqrt {\frac {k}{M}}}} and the fundamental natural frequency, f = 2 you can try here {\displaystyle f={\frac {\omega }{2\pi }}} . Knowledge of point physics, […]
