maximum displacement

Postby Guest » Wed Jan 08, 2020 10:12 am

A simply supported beam is subjected to two vibrations along its length, emanating from two machines at opposite ends of the beam. The displacement caused by the vibrations can be modelled by the following equations.
x1=5sin(100π+π/2)
x2=6.5sin(100π-π/3)
when both machines are swithced on, how long does it take for each machine to produce its maximum displacement?
