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 Over-damped Without vibrations Under damped Critically damped Over-damped Without vibrations Under damped Critically damped ANSWER DOWNLOAD EXAMIANS APP

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 tp /4 16 tp tp /16 4 tp tp /4 16 tp ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A shaft has an attached disc at the centre of its length. The disc has its centre of gravity located at a distance of 2 mm from the axis of the shaft. When the shaft is allowed to vibrate in its natural bow-shaped mode, it has a frequency of vibration of 10 rad/s. When the shaft is rotated at 300 r.p.m., it will whirl with a radius of 2.50 mm 2.22 mm 2 mm 3.0 mm 2.50 mm 2.22 mm 2 mm 3.0 mm ANSWER DOWNLOAD EXAMIANS APP
