Also, determine the amplitude of the steady-state response for 8(t) if a 10 Newton force

is applied to the mass as indicated in the figure with a frequency of 10 rad/s; that is, F(t) = 10 cos at

where = 10rad / s.

A uniform bar of mass mis pivoted at O and supported at the ends by two springs as shown in the

figure below. End P of the spring PQ is subjected to a sinusoidal displacement x(t) = x₁ sin cot.

Given: 1=1m, k=1000N/m, c=500N-s/m, m=10kg,x=1cm, and = 10rad/s. In

addition,
