Theory of Machine A system in dynamic balance implies that There will absolutely no wear of bearings There is no critical speed in the system The system is also statically balanced The system is critically damped There will absolutely no wear of bearings There is no critical speed in the system The system is also statically balanced The system is critically damped ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A spring controlled governor is said to be isochronous when the controlling force Decreases as the radius of rotation increases Increases as the radius of rotation decreases Remain constant for all radii of rotation Increases as the radius of rotation increases Decreases as the radius of rotation increases Increases as the radius of rotation decreases Remain constant for all radii of rotation Increases as the radius of rotation increases ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The rotating shafts tend to vibrate violently at whirling speeds because Bearing centre line coincides with the axis Resonance is caused due to the heavy mass of the rotor The system is unbalanced The shafts are rotating at very high speeds Bearing centre line coincides with the axis Resonance is caused due to the heavy mass of the rotor The system is unbalanced The shafts are rotating at very high speeds ANSWER DOWNLOAD EXAMIANS APP
