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(φ - α) P = W tan(α - φ) P = W cos(α + φ) P = W tan(α + φ) P = W tan(φ - α) P = W tan(α - φ) P = W cos(α + φ) P = W tan(α + φ) ANSWER DOWNLOAD EXAMIANS APP
