Failure Mechanism 2

η = \frac{τ_{x, netto}}{f_{v, n e t t o}} = \frac{\frac{n_{x y} e_{x}}{b_{x} \sum_{i, y} t_{i}}}{f_{v, n e t t o}} \leq 1

η = \frac{τ_{y, netto}}{f_{v, n e t t o}} = \frac{\frac{n_{x y} e_{y}}{b_{y} \sum_{i, x} t_{i}}}{f_{v, n e t t o}} \leq 1

n_xy	Shear force
e_x, e_y	Plank width with gap in the x or y direction
b_x, b_y	Plank width in the x or y direction
