The structure shown can be treated as damped single degree of freedom

The structure shown can be treated as damped single degree of freedom with damping constant (C=78872 N.s/m), assume all the members to be massless, the structure is subjected to a harmonic load (force 119980.2* sin 12.06 t). a) For the resulting vibration, determine the max dynamic horizontal displacement of the mass b) Determine the max dynamic bending moment at the critical section The 3m 1.5m A D I 4m mass = 5096 kg/m B E 21 5m link 4m F 21 119980.2* sin 12.06 t k (link) =383203 N/m E=2*10 N/m I= 0.001 m 10 1308
