This is an example of using the Laplace transform to solve the forced response of a SDOF system to harmonic excitation.
Theory problem: forced response of SDOF system to half-sine excitation by Laplace transform
This is an example of using the Laplace transform to solve the forced response of a mechanical system. In this example the system is excited by a half-sine pulse, which is common in, for example, vibration testing. The supplied zip file contains a pdf file with the problem definition, and a separate zip file with a suggested solution. Like the harmonic SDOF forced response example, the present example is also an example I let all my mechanical vibration students solve.
