: The Mass And Stiffness Coefficients Of The Mass Spring Damper System Are 20 Kg And 40 N Cm Respectively Vibrating Force 2 (56.44 KiB) Viewed 29 times

The mass and stiffness coefficients of the mass-spring-damper system are 20 kg and 40 N/cm respectively. vibrating force 20sin(10t-30°)N is directly applied to the mass and when the initial conditions (0) = x(0)=0 the response of the system is Find the answer. (a) unattenuated, (b)viscous damping coefficient=2N/(cm/s). ܘ ܘ ܘ ܘ
(a) x = -0.79 cos (10 √2t-2.2555)+sin (10t-π/6) cm, (b) x= 0.49 e 5t cos (5 √7t-0.1736) +0.5sin (10t-5/12) cm
