Simplify x(t) into the standard sinusoidal form: x(t) = Acos(wt+ phi) Define x(t) as x(t) = cos(wt-pi) + cos(wt+pi/3)+2cos(wt-pi/3)
Define x(t) as x(t) = 2 cos(ωt + 5) + 8 cos(ωt + 9) + 4 cos(ωt) where the phases have units of radians. Express x(t) in the form x(t) = Acos(ωt + ϕ). Use a calculator to add the complex phasors to obtain the answer. Explain your answer by giving a vector diagram of the phasors.

Consider the mass M subject to periodic forcing P(t) A sin wt where A 0.3 and e is a small parameter. The mass is attached to a spring with stiffness k and dashpot with damping coefficientc to model the stiffness and damping of the structure. Resting atop the idealized structure is vibration damper consisting of a mass ma, spring ka, and dashpot ca, as shown in Figure 1. The goal is to make the appropriate choice of the parameters ma,...
