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 When the addenda on pinion and wheel is such that the path of approach and path of recess are half of their maximum possible values, then the length of the path of contact is given by (where r = Pitch circle radius of pinion, R = Pitch circle radius of wheel, and φ = Pressure angle) [(r² + R²) sinφ]/2 [(r + R) sinφ]/2 [(r² + R²) cosφ]/2 [(r + R) cosφ]/2 [(r² + R²) sinφ]/2 [(r + R) sinφ]/2 [(r² + R²) cosφ]/2 [(r + R) cosφ]/2 ANSWER DOWNLOAD EXAMIANS APP
