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 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 difficulty in manufacturing cam profile Because of loose contact of follower with cam surface 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 difficulty in manufacturing cam profile Because of loose contact of follower with cam surface ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When the crank is at the outer dead centre, in a reciprocating steam engine, then the acceleration of the piston will be ω² r {n/(n - 1)} ω² r {n/(n + 1)} ω² r {(n + 1)/n} ω² r {(n - 1)/n} ω² r {n/(n - 1)} ω² r {n/(n + 1)} ω² r {(n + 1)/n} ω² r {(n - 1)/n} ANSWER DOWNLOAD EXAMIANS APP
