A spring is stretched 6 inches by a mass that weighs 8 lb. The mass is attached to a dashpot mechanism that has a damping constant of 0.25 lb-sec/ft and is acted on by an external force of 4cos(2t) lb.
a) Determine the steady-state response of this system
b) If the given mass is replaced by a mass m, determine the value of m for which the amplitude of the steady-state response is maximum.
I got part a but didnt get part b... I am not sure where to start... can anyone tell me how to start it? or any tips?
ps the answer to a is U(t) = (8/901)(30cos(2t)+sin(2t)) ft
thanks
