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
Two heavy rotating masses are connected by shafts of lengths l₁, l₂ and l₃ and the corresponding diameters are d₁, d₂ and d₃. This system is reduced to a torsionally equivalent system having uniform diameter d = d₁ of the shaft. The equivalent length of the shaft is

l = l₁ + l₂.(d₁/d₂)³ + l₂.(d₁/d₃)³

(l₁ + l₂ + l₃)/3

l = l₁ + l₂.(d₁/d₂)⁴ + l₃.(d₁/d₃)⁴

l₁ + l₂ + l₃

l = l₁ + l₂.(d₁/d₂)³ + l₂.(d₁/d₃)³

(l₁ + l₂ + l₃)/3

l = l₁ + l₂.(d₁/d₂)⁴ + l₃.(d₁/d₃)⁴

l₁ + l₂ + l₃
