A machine, of mass 17 kg, is mounted on a spring having stiffness 1 N/mm. A piston within the machine of mass 2 kg has a reciprocating motion with a stroke of 75 mm and a speed of 5000 rpm. Assuming the motion to be SHM, determine
- amplitude of motion of the machine
- fore transmitted to the ground
Damping ratio may be taken as 0.20
