Theory of Machine If the damping factor for a vibrating system is unity, then the system will be Over damped Critically damped Without vibrations Under damped Over damped Critically damped Without vibrations Under damped ANSWER DOWNLOAD EXAMIANS APP
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 Without vibrations Over-damped Critically damped Under damped Without vibrations Over-damped Critically damped Under damped ANSWER DOWNLOAD EXAMIANS APP
