Problem 2) Frequencies and mode shapes of a damped 2 DOF system are given as: E m Where K = stiffness and m = mass. The mode shapes corresponding to wo, is (4¹) = 411.3) an (02 is (4²) = A²1 {-781) Note: The above modes are the natural modes. @₁ = 1.19 and w₂ = 2.36 m and corresponding to If the system is excited by F₁ (t) = u(t), where u(t) is the unit step function, determine not need to solve the integral. Note: F₂(t)=0, 5= where is the damping ratio, q:(0)=0, q2(0)=qo and q₁ = 0,42 = Vo 30 pts (x₂ (t)) You do (x₂ (t))
