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 In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because the uniform velocity motion is a partial parabolic motion Because of loose contact of follower with cam surface Because of difficulty in manufacturing cam profile In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because the uniform velocity motion is a partial parabolic motion Because of loose contact of follower with cam surface Because of difficulty in manufacturing cam profile ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The static balancing is satisfactory for low speed rotors but with increasing speeds, dynamic balancing becomes necessary. This is because, the Effects of unbalances are directly proportional to the speed Unbalanced forces are not dangerous at higher speeds Unbalanced couples are caused only at higher speeds Effects of unbalances are proportional to the square of the speed Effects of unbalances are directly proportional to the speed Unbalanced forces are not dangerous at higher speeds Unbalanced couples are caused only at higher speeds Effects of unbalances are proportional to the square of the speed ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The Grubler's criterion for determining the degrees of freedom (n) of a mechanism having plane motion is (where l = Number of links, and j = Number of binary joints) n = 3(l - 1) - 2j n = 2(l - 1) - 2j n = 4(l - 1) - 3j n = (l -1) - j n = 3(l - 1) - 2j n = 2(l - 1) - 2j n = 4(l - 1) - 3j n = (l -1) - j ANSWER DOWNLOAD EXAMIANS APP
