Theory of Machine A body of weight W is required to move up the rough inclined plane whose angle of inclination with the horizontal is α. The effort applied parallel to the plane is given by (where μ = tan φ = Coefficient of friction between the plane and the body) P = W (cos α + μ sin α) P = W tan (α + φ) P = W tan α P = W (sin α + μ cos α) P = W (cos α + μ sin α) P = W tan (α + φ) P = W tan α P = W (sin α + μ cos α) ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The total number of instantaneous centers for a mechanism consisting of n links are n/2 n n - 1 n(n - 1)/2 n/2 n n - 1 n(n - 1)/2 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 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
