If the machine of Problem is mounted on a large concrete block of mass 1136 kg and the stiffness of the springs or pads under the block is increased so that the statical deflection is still 0.508 cm, wh at will be the dynamic amplitude?
Problem
An industrial machine of mass 453.4 kg is supported on springs with a static deflection of 0.508 cm. If the machine has a rotating unbalance of 0.2303 kg . m, determine (a) the force transmitted to the floor at 1200 rpm and (b) the dynamic amplitude at this speed. (Assurne damping to be negligible.)
