The ratio of driving tensions for flat belts, neglecting centrifugal tension, is (where T₁, and T₂ = Tensions on the tight and slack sides of belt respectively, μ = Coefficient of friction, between the belt and pulley, and θ = Angle of contact)

T₁/T₂ =eμθ

T₁/T₂ = log μθ

T₁/T₂ = μθ

log (T₁/T₂) = μθ

T₁/T₂ =eμθ

T₁/T₂ = log μθ

T₁/T₂ = μθ

log (T₁/T₂) = μθ
