How to Calculate and Solve for Shear Angle | Merchant Force Circle

The image above represents shear angle. To calculate shear angle, two essential parameters are needed and these parameters are Rake Angle (in Degrees) (α) and Angle of Friction (in Degrees) (β).

The formula for calculating shear angle:

φ = 45° + ^α / ₂ – ^β / ₂

Where:

φ = Shear Angle (φ)
α = Rake Angle
β = Angle of Friction

Let’s solve an example;
Find the shear angle when the rake angle is 34 and the angle of friction is 28.

This implies that;

α = Rake Angle = 34
β = Angle of Friction = 28

φ = 45° + ^α / ₂ – ^β / ₂
That is, φ = 45° + ^34° / ₂ – ^28° / ₂
φ = 45° + 17° – 14°
φ = 48°

Therefore, the shear angle is 48°.
