Webis the amplitude or maximum value of the force transmitted to the base. Hence: 2 2 2 2 2 12 12 T r F m Y rr] Z] from which we get: 2 2 2 2 1 2 1 (2 ) r r r r kY F T]] In this relationship, kY represents the force on the mass if it remained stationary, while the base moved with only the spring attached. This ratio is called the force ... WebLet a force F(t) is also applied to the mass. The inertial force ࠵?, the damping force ࠵? ࠵? and the spring force kx act opposite to the applied force F(t) and hence the governing equation is now; ࠵? ࠵? + ࠵? ࠵? + ࠵?࠵? = ࠵? (࠵?) If F(t)=0 then the system is called damped free vibration If F(t) ≠ 0 it is called damped ...
