Question

A mass of 1kg is suspended from a spring of stiffness constant 25N/m. If the undamped frequency is2/√3times the damped frequency,calculate the damping factor.​

Answer 1

Answer:

The natural undamped frequency is given by

f

n

=

=15.26Hz

The damped frequency is given by

f=f

n

1−δ

=15.26×

1−0.09

=14.56Hz
