According to parallel axis theorem, the moment of inertia of a section about an axis parallel to the axis through center of gravity (i.e. IP) is given by(where, A = Area of the section, IG = Moment of inertia of the section about an axis passing through its C.G., and h = Distance between C.G. and the parallel axis.)

According to parallel axis theorem, the moment of inertia of a section about an axis parallel to the axis through center of gravity (i.e. IP) is given by(where, A = Area of the section, IG = Moment of inertia of the section about an axis passing through its C.G., and h = Distance between C.G. and the parallel axis.)

IP = IG + Ah2

IP = IG - Ah2

IP = Ah2 / IG

IP = IG / Ah2

IP = IG + Ah2

IP = IG - Ah2

IP = Ah2 / IG

IP = IG / Ah2

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 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)

P = W tan (φ - α)

P = W tan (α - φ)
