Chapter 9, Problem 9.22P

An electronics module used to control a large crane must be isolated from the crane’s motion. The module weighs 2 lb. (a) Design an isolator so that no more than 10% of the crane's motion amplitude is transmitted to the module. The crane's vibration frequency is 3000 rpm. (b) What percentage of the crane's motion w ill be transmitted to the module if the crane's frequency can be anywhere between 2500 and 3500 rpm?

A vibrating machine is isolated from the floor using springs. If the ratio of excitation frequency of vibration of machine to the natural frequency of the isolation system is equal to 0.5, calculate the transmissibility ratio of isolation.
When a 2kg cylinder is suspended from a spring, the spring is stretched by a distance of 40 mm. What will be the natural frequency in Hz (use four decimal places) for aa 0.5 kg cylinder suspended from the same spring?
The little brown bat is a common bat species in North America. It emits echolocation pulses at a frequency of 40 kHz, well above the range of human hearing. To allow observers to “hear” these bats, the bat detector as shown combines the bat’s sound wave at frequency f1 with a wave of frequency f2 from a tunable oscillator. The resulting beat frequency is isolated with a filter, then amplified and sent to a loudspeaker. To what frequency should the tunable oscillator be set to produce an audible beat frequency of 3 kHz?
