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.
