Theory of Machine The efficiency of a screw jack is maximum, when (where α = Helix angle, and φ = Angle of friction) α = 90° - φ α = 90° + φ α = 45° - φ/2 α = 45° + φ/2 α = 90° - φ α = 90° + φ α = 45° - φ/2 α = 45° + φ/2 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The dynamic friction is the friction experienced by a body, when the body Is at rest None of these Just begins to slide over the surface of the other body Is in motion Is at rest None of these Just begins to slide over the surface of the other body Is 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 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 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 ANSWER DOWNLOAD EXAMIANS APP
