A vibration isolation block is to be installed in a laboratory so that the vibration form adjacent factory operations will not disturb certain experiments. If the weight of the isolation block is 800 lb and it vibrates vertically with an amplitude of 0.03 in at 20 Hz, determine the stiffness of the isolation system required to reduce the vertical-motion amplitude to 0.005 in. Neglect damping.

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.
