WebOct 28, 2024 · At corner B’ the line B’C’ is tilted inward hence its respective shear angle `\gamma_{B1}` is negative. While line AB’ at corner B’ is also tilted inward so the shear angle `\gamma_{B2}` also becomes negative. Thus the total shear angle at the corner B’ can be found by taking the sum of both shear angles.
