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