Consider a harmonically forced m-c-k system shown below.The particular solution to the harmonic input force, ƒ (t) =F cos|x(1)=Xcos(1+0).F cos().isAs the input frequency is varied, the response amplitude also varies. What is the maximum response amplitude (in meters)? Do not include units. Usescientific notation with three significant figures.Let m = 1 kg, c = 6 N-s/m, k = 112 N/m, and F = 111 N.Note that the numbers are chosen so that the maximum peak response exists (1-23²>0).

For the system shown in Figure 2, u (t) and y (t) denote the absolute displacements of Building A and Building B, respectively. The two buildings are connected using a linear viscous damper with damping coefficient c. Due to construction activity, the floor mass of Building B was estimated that vibrates with harmonic displacement that is described by the following function: y(t) = y,cos (wt). k/2 Building A H k/2 M(t) C 73(1) Building B Equivalent (Building A) 00000000 Figure 2: Single-degree-of-freedom system in Problem 2. 111 uft) Please compute the following related to Building A: (a) Derive the equation of motion of the mass m.

vibrations please help
please find the soultion and explain will upvote if correct
1) For the mass-damper system at right, the model in terms of velocity is mv + cv = f. The time constant of this first order system is t = m/c. For this system, a larger value of the damping constant c causes the time constant to decrease - which is counterintuitive. It seems that a small amount of damping should correspond to a system with a fast response. How can you reconcile this? m CA
