Input Parameters

F = - kN

Rod Type = -

α = - degrees

μ = -

μ' = -

Rod Properties (from DIN Standard)

D_min = - mm

D1 = - mm

P = - mm

Key_Width = - mm

Normal_Fit_Hole = - mm

Intermediate Calculations

rm = D1 / 2 = - mm

φ = atan(P / (π × D_min)) = - degrees

ε₁ = atan(μ / cos(α)) = - degrees

r'm = (Key_Width + Normal_Fit_Hole) / 4 = - mm

Final Results

Mγ = F × tan(φ + ε₁) × rm = - Nm

Ms = μ' × F × r'm = - Nm

M = Mγ + Ms = - Nm
