Theory of Machine When the belt is stationary, it is subjected to some tension known as initial tension. The value of this tension is equal to the Sum of the tensions on the tight side and slack side of the belt Tension in the slack side of the belt Tension in the tight side of the belt Average tension of the tight side and slack side of the belt Sum of the tensions on the tight side and slack side of the belt Tension in the slack side of the belt Tension in the tight side of the belt Average tension of the tight side and slack side of the belt 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
