problem 1)a) State degree of freedom of a vibratory system.

b) Name the three elementary parts of a vibrating system?

c) What is a semi definite system?

d) What are the common types of damping?

e) What do you undrstand by beat phenomenon?

f) What is vibration isolation?

g) Mention two practical exs of critical damping.

h) What is principal co-ordinates?

i) prepare down the name of seismic instruments.

j) What are influence co-efficients?

In a spring mass system, the mass of 10 kg makes 40 oscillations in 20 seconds without damper. With damper, the amplitude decreases to 0.20 of the original; value after 5 oscillations.

Find out: (a) Stiffness of the spring.

(b) Logarithmic decrement.

(c) Damping factor.

(d) Damping co-efficient.

problem 4) Sketch a neat sketch of centrifugal pendulum absorber and describe its working.
