Theory of Machine The acceleration of a particle at any instant has two components i.e. radial component and tangential component. These two components will be Opposite to each other Inclined at 45° Parallel to each other Perpendicular to each other Opposite to each other Inclined at 45° Parallel to each other Perpendicular to each other ANSWER DOWNLOAD EXAMIANS APP
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 (sin α + μ cos α) P = W tan (α + φ) P = W tan α P = W (cos α + μ sin α) P = W (sin α + μ cos α) P = W tan (α + φ) P = W tan α P = W (cos α + μ sin α) ANSWER DOWNLOAD EXAMIANS APP
