Theory of Machine In a screw jack, the effort required to lift the load W is given by (where α = Helix angle, and φ = Angle of friction) P = W tan(α - φ) P = W tan(φ - α) P = W cos(α + φ) P = W tan(α + φ) P = W tan(α - φ) P = W tan(φ - α) P = W cos(α + φ) P = W tan(α + φ) 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 (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) P = W (sin α + μ cos α) P = W tan (α + φ) P = W tan α ANSWER DOWNLOAD EXAMIANS APP
