Question: The instrument is centered uniformly on a platform P, which in turn is supported by four springs, each spring having stiffness k. If the floor

The instrument is centered uniformly on a platform P, which in turn is supported by four springs, each spring having stiffness k. If the floor is subjected to a vibration f, having a vertical displacement amplitude δ₀, determine the vertical displacement amplitude of the platform and instrument. The instrument and the platform have a total weight W. Given: k = 130 f = 7 Hz ft 50 80 = 0.17 ft W = 18 lb

Given: k = 130 f = 7 Hz ft 50 80 = 0.17 ft W = 18 lb
