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