State and explain D’ Alembert’s principle.

Set up the equation of motion and hence determine the natural frequency for
small vertical vibrations of the idealization shown in figure.

Massless beam

1.

Take L = 3m. EI for beam = 27 Nm’, stiffness for each spring, k = 3 N/m and
mass m= 3 kg

A 50 kg turbine is mounted on four parallel springs, each of stiffness 3 x 10°
N/m. When the machine operates at 20 Hz, its steady-state amplitude is observed
as 1.8 mm. Compute the magnitude of the excitation?
