Consider the damped forced motion described by d'y c dy di? k Fo cos ot. |- m dt m m We have shown that the steady-state solution can be written in the form Fo cos(ot – v), H Yp(t) = where m(w – o?) со sin v = H COS V = H k m H = /m2(03 – 0²)2 + c?w?. Assuming that c2/(2m²w}) < 1, show that the ampli- tude of the steady-state solution is a maximum when c2 0 = 2m2 [Hint: The maximum occurs at the value of w that makes H a minimum. Assume that H is a function of w, and determine the value of w that minimizes H.]
