Question
If the beam is made from wood having an allowable shear stress $\tau_{\text {allow }}=400$ psi, determine the maximum magnitude of $\mathbf{P}$. Set $d=4$ in.
Step 1
Since the problem does not provide the width, we will assume it to be a square cross-section, so $b = d = 4$ in. Now, we can calculate the section modulus: $S = \frac{4 \times 4^2}{6} = \frac{64}{6} = 10.67$ in^3 Show more…
