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 (sin α + μ cos α)

P = W tan α

P = W (cos α + μ sin α)

P = W tan (α + φ)

P = W (sin α + μ cos α)

P = W tan α

Theory of Machine
For an isochronous Hartnell governor (where r₁ and r₂ = Maximum and minimum radius of rotation of balls respectively, S₁ and S₂ = Maximum and minimum force exerted on the sleeve respectively, and M = Mass on the sleeve)

S₂/S₁ = r₁/r₂

(m.g - S₁)/(m.g - S₂) = r₂/r₁

(m.g + S₁)/(m.g + S₂) = r₁/r₂

S₁/S₂ = r₁/r₂

S₂/S₁ = r₁/r₂

(m.g - S₁)/(m.g - S₂) = r₂/r₁

(m.g + S₁)/(m.g + S₂) = r₁/r₂

S₁/S₂ = r₁/r₂
