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 the uniform velocity motion is a partial parabolic motion Because of difficulty in manufacturing cam profile 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 the uniform velocity motion is a partial parabolic motion Because of difficulty in manufacturing cam profile ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a flat collar pivot bearing, the moment due to friction is proportional to (r₁² - r₂²)/(r₁ - r₂) (r₁² - r₂²)/(r₁ + r₂) (r₁³ - r₂³)/(r₁ - r₂) (r₁³ - r₂³)/(r₁² - r₂²) (r₁² - r₂²)/(r₁ - r₂) (r₁² - r₂²)/(r₁ + r₂) (r₁³ - r₂³)/(r₁ - r₂) (r₁³ - r₂³)/(r₁² - r₂²) ANSWER DOWNLOAD EXAMIANS APP
