Reference no: EM1383608

A single-cylinder enginer has a total mass of 150 kg. Its reciprocating mass is 5 kg and the rotating mass is 2.5 kg. The stroke (2r) is 15 cm and the speed is 600 rpm.

a) If the enginer is mounted floatiing on very weak spring, what is the amplitude of the vertical vibration of the engine?

b) If the engine is mounted solidly on a rigid foundation, what is the alternating force amplitude transmitted? Assume the connection rod to be of infinite length.
