Question

• Assuming resonance to have occurred at a frequency of 30 cycles / sec in a vertical vibration of a test block 1mx1mx1m. Determine the coefficient of elastic compression. The weight of the oscillator is 800 N and the force produced by it after 15 cycles is 1500 N. Compute the maximum amplitude in the vertical direction at 15 cycles per sec. Weight of the test block is 24 kN/m.

I want neat and correct answer with proper explanation otherwise negative ratings
