Theory of Machine In an open pair, the two elements of a pair Have a line or point contact when in motion Are not held together mechanically Are kept in contact by the action of external forces, when in motion Have a surface contact when in motion Have a line or point contact when in motion Are not held together mechanically Are kept in contact by the action of external forces, when in motion Have a surface contact when in motion 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 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
