For a symmetrically distributed triangular load, the shear stress τxz at any point at a depth z is given by ___________

\(τ_{xz}=-\frac{q}{π} \left[α_1+α_2 \right]\)

\(τ_{xz}=-\frac{qz}{aπ} \left[α_1-α_2 \right] \)

\(τ_{xz}=-\frac{q}{π} \left[α_1+α_2 \right]\)

\(τ_{xz}=-\frac{q}{π} \left[\frac{az}{a^2+z^2}\right]\)

\(τ_{xz}=-\frac{q}{π} \left[α_1-α_2 \right] \)
