Theory of Machine The maximum fluctuation of speed is the Variations of speed above and below the mean resisting torque line Difference of minimum fluctuation of speed and the mean speed Difference of the maximum and minimum speeds Sum of maximum and minimum speeds Variations of speed above and below the mean resisting torque line Difference of minimum fluctuation of speed and the mean speed Difference of the maximum and minimum speeds Sum of maximum and minimum speeds 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 Because of difficulty in manufacturing cam profile Because the uniform velocity motion is a partial parabolic motion In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because of loose contact of follower with cam surface Because of difficulty in manufacturing cam profile Because the uniform velocity motion is a partial parabolic motion In order to have acceleration in beginning and retardation at the end of stroke within the finite limits ANSWER DOWNLOAD EXAMIANS APP
