Theory of Machine In multi V-belt transmission, if one of the belt is broken, we have to change the Broken belt There is no need of changing any one as remaining belts can take care of transmission of load All the belts Broken belt and its adjacent belts Broken belt There is no need of changing any one as remaining belts can take care of transmission of load All the belts Broken belt and its adjacent belts 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 2.22 mm 2 mm 3.0 mm 2.50 mm 2.22 mm 2 mm 3.0 mm 2.50 mm ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a cam drive with uniform velocity follower, the sharp corners of the displacement diagram are rounded off at the beginning and at the end of each stroke. This is done Because of loose contact of follower with cam surface In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because of difficulty in manufacturing cam profile Because the uniform velocity motion is a partial parabolic motion Because of loose contact of follower with cam surface In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because of difficulty in manufacturing cam profile Because the uniform velocity motion is a partial parabolic motion ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The rotating shafts tend to vibrate violently at whirling speeds because The system is unbalanced The shafts are rotating at very high speeds Resonance is caused due to the heavy mass of the rotor Bearing centre line coincides with the axis The system is unbalanced The shafts are rotating at very high speeds Resonance is caused due to the heavy mass of the rotor Bearing centre line coincides with the axis ANSWER DOWNLOAD EXAMIANS APP
