consider a square flexible membrane 4cm on a side with density 10-?g/cm? at tension 106 dynes/cm. let the membrane be driven with the force of 10-4coswt dynes/cm? which is the amplitude of the displacement of the mid point at frequencies 400, 800, 1200, 1600, 1800, 2000 cycle per secon? Note there is no damping on this ideal membrane. correction to the question. it's what is the amplitude not which is the amplitude take note please
