Theory of Machine In a multiple V-belt drive, when a single belt is damaged, it is preferable to change the complete set to Ensure uniform loading Reduce slip Reduce vibration Ensure proper alignment Ensure uniform loading Reduce slip Reduce vibration Ensure proper alignment 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 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 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 ANSWER DOWNLOAD EXAMIANS APP
