Theory of Machine A machine mounted on a single coil spring has a period of free vibration of tp . If the spring is cut into four equal parts and placed in parallel and the machine is mounted on them, then the period of free vibration of the new system will become tp /16 4 tp 16 tp tp /4 tp /16 4 tp 16 tp tp /4 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 Under damped Critically damped Without vibrations Over-damped Under damped Critically damped ANSWER DOWNLOAD EXAMIANS APP
