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 of loose contact of follower with cam surface Because of difficulty in manufacturing cam profile Because the uniform velocity motion is a partial parabolic motion In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because of loose contact of follower with cam surface Because of difficulty in manufacturing cam profile Because the uniform velocity motion is a partial parabolic motion ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine Two pulleys of radii r₁ and r₂ and at distance x apart are connected by means of a cross belt drive. The length of the belt is π (r₁ + r₂) + [(r₁ - r₂)²/x] + 2x π (r₁ - r₂) + [(r₁ - r₂)²/x] + 2x π (r₁ + r₂) + [(r₁ + r₂)²/x] + 2x π (r₁ - r₂) + [(r₁ + r₂)²/x] + 2x π (r₁ + r₂) + [(r₁ - r₂)²/x] + 2x π (r₁ - r₂) + [(r₁ - r₂)²/x] + 2x π (r₁ + r₂) + [(r₁ + r₂)²/x] + 2x π (r₁ - r₂) + [(r₁ + r₂)²/x] + 2x ANSWER DOWNLOAD EXAMIANS APP
