Question

a telephone diaphragm executes damped vibration .for a displacement of 0.01 mm the restoring force is 10^4 dyne .the retarding force is 4×10^3 dynes for a velocity of 2 .5 cm /sec if the effective mass of the diaphragm ,treated as a particle is 1 gm( 1) what is the angular frequency ??( 2)write down the differential equation of motion
​

Answer 1

Answer:

A vibrometer having a natural frequency of 4 rad/s and ξ=0.3 is attached to a structure that performs a harmonic motion. If the difference ...
