A vibrating structural beam in a spacecraft can cause problems if the frequency of vibration is fairly high. Even if the amplitude of vibration is only a fraction of a millimeter, the acceleration of the beam can be several times greater than the acceleration due to gravity. As an example, find the maximum acceleration of a beam that vibrates with an amplitude of 0.37 mm at the rate of 104 vibrations per second. Give your answer as a multiple of g.
An unstretched spring has a length of 0.30 m. while the spring is stretched to a total length of 0.60 m, it supports traveling waves moving at 4.5 m/s. How fast would waves travel on this spring if it is stretched to 0.90 m.
