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 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 difficulty in manufacturing cam profile Because of loose contact of follower with cam surface 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 difficulty in manufacturing cam profile Because of loose contact of follower with cam surface ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The displacement of the reciprocating roller follower, when it has contact with the straight flanks of the tangent cam, is given by (where r₁ = Minimum radius of the cam, r₂ = Radius of the roller follower, and θ = Angle turned by the cam from the beginning of the follower displacement) (r₁ - r₂) (1 - cosθ) (r₁ - r₂) [(1 - cosθ)/cosθ] (r₁ + r₂) (1 + cosθ) (r₁ + r₂) [(1 - cosθ)/cosθ] (r₁ - r₂) (1 - cosθ) (r₁ - r₂) [(1 - cosθ)/cosθ] (r₁ + r₂) (1 + cosθ) (r₁ + r₂) [(1 - cosθ)/cosθ] ANSWER DOWNLOAD EXAMIANS APP

Theory of Machine A shaft has an attached disc at the centre of its length. The disc has its centre of gravity located at a distance of 2 mm from the axis of the shaft. When the shaft is allowed to vibrate in its natural bow-shaped mode, it has a frequency of vibration of 10 rad/s. When the shaft is rotated at 300 r.p.m., it will whirl with a radius of 2.22 mm 3.0 mm 2.50 mm 2 mm 2.22 mm 3.0 mm 2.50 mm 2 mm ANSWER DOWNLOAD EXAMIANS APP
