Q1/ For the system shown in the figure below: x₁(t) X2(1) fv3 f(t) K₁ K3 0000 Mi K₂ M2 0000 0000 fv₂ fv₁ Where: K1...3 are springs' constants, M₁1,2 are masses, fv1...3 are viscous friction factors, f(t) is the input force, and x1,2 are the motion displacements. A. Derive the mathematical model of the system, B. Find the Transfer Function X2(s)/F(s). C. Simulate the system in the MatLab/Simulink using step input signal, assuming all constant variables.
