Theory of Machine The equation of motion for a vibrating system with viscous damping is (d²x/dt²) + (c/m). (dx/dt) + (s/m). x = 0. If the roots of this equation are real, then the system will be Critically damped Without vibrations Under damped Over-damped Critically damped Without vibrations Under damped Over-damped ANSWER DOWNLOAD EXAMIANS APP
