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 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 Because of difficulty in manufacturing cam profile Because the uniform velocity motion is a partial parabolic motion ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine A machine mounted on a single coil spring has a period of free vibration of tp . If the spring is cut into four equal parts and placed in parallel and the machine is mounted on them, then the period of free vibration of the new system will become tp /16 tp /4 4 tp 16 tp tp /16 tp /4 4 tp 16 tp ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The Kutzbach criterion for determining the number of degrees of freedom (n) is (where l = number of links, j = number of joints and h = number of higher pairs) n = 3(l - 1) - 3j - h n = 2(l - 1) - 2j - h n = 3(l - 1) - 2j - h n = 2(l - 1) - 3j - h n = 3(l - 1) - 3j - h n = 2(l - 1) - 2j - h n = 3(l - 1) - 2j - h n = 2(l - 1) - 3j - h ANSWER DOWNLOAD EXAMIANS APP
