**Inclined Wedge Force and Friction Equation and Calculator**

Force is applied Horizontal to Wedge/Angled and Perpendicular to Horizontal Surface

**Neglecting Friction**:

P = 2 · Q · tan α

P = 2 · Q · b / *h*

Q = 0.5 · P · cotα

Q = P ·* h * / (2b)

**With Friction**:

P = 2 · Q · tan (α + φ )

µ = Coefficient of Friction = tan φ

**Where**:

P = Load (lbs, N)

Q = Load (lbs, N)

α = Angle (deg.)

φ = Coefficient of Friction constant

µ = Coefficient of Friction

b = Length (in,mm)

*h *= Length (in,mm)
