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 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 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 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine A rigid body, under the action of external forces, can be replaced by two masses placed at a fixed distance apart. The two masses form an equivalent dynamical system, if All of these The center of gravity of the two masses coincides with that of the body The sum of the two masses is equal to the total mass of body The sum of mass moment of inertia of the masses about their center of gravity is equal to the mass moment of inertia of the body All of these The center of gravity of the two masses coincides with that of the body The sum of the two masses is equal to the total mass of body The sum of mass moment of inertia of the masses about their center of gravity is equal to the mass moment of inertia of the body ANSWER DOWNLOAD EXAMIANS APP
