3. A compressor of mass 700 kg has undamped spring mountings which deflect by 0.5 mm under its weight. This compressor, on its mountings, is installed on a flexible floor whose mass of 1400 kg may be considered as concentrated below the compressor. The floor has negligible damping. The highest natural frequency of vertical vibration of this combined system must not exceed 1.5 times that of the compressor with its spring mountings on a rigid foundation. Find a suitable value...

A centrifugal pump of mass 500 kg is mounted on a flexible support causing the support to deflect by 6 mm. The ratio of damping coefficient to the critical damping coefficient for the support is found to be 0.15. When the pump running at 500 rev/min, an amplitude of vibration of 5 mm is measured. Analyse the value of disturbing force created by the pump during its operation. Please show answer step by step.

Q-3 (25 pts) An industrial machine of total mass M-600 kg is supported on springs with a static deflection of 5.9 mm. The machine has a rotating unbalance of m40 kg (part of the total mass) at an effective eccentricity of es3.0 mm. Determine the amplitude of resulting vibration and phase angle when the unbalance rotates at -350 rpm. The system is damped with a dashpot of ce 15000 Ns/m. M Consider only vertical effects

QUESTION 2
Consider an electrical motor with mass M = 901.8129 kg
located at the middle of pinned-pinned beam, as shown in the figure
below. Assume that the Young’s modulus of the beam E =
8.5470x1010 Pa, moment of inertia I =
8.3375x104 mm4 , length of the beam
L = 0.2859 m and zero initial conditions. If there is an
unbalance mass of m0 = 2.3714 kg in the
rotating part of the motor, eccentricity is e = 4.1473...
