6) The 11-ft long overhanging timber beam AE is to be designed to support the loading shown in the previous problem. The actual width of the beam is 3.5 inches. The timber has an allowable bending stress of 1.75 ksi. a. What is the minimum required depth, h of the beam? b. If $T_{allow}$ is 0.250 ksi, is the design acceptable for shear?

Step 1
To calculate the bending moment, we need to find the force acting at point E and the distance from point E to the support. Given: Length of the beam, AE = 11 ft Loading shown in the diagram From the diagram, we can see that there is a 2 kip load at point E. Show more…

Determine the minimum depth $h$ of the beam to the nearest $\frac{1}{8}$ in. that will safely support the loading shown. The allowable bending stress is $\sigma_{\text {allow }}=21 \mathrm{ksi}$ and the allowable shear stress is $\tau_{\text {allow }}=10 \mathrm{ksi} .$ The beam has a uniform thickness of 3 in.
The timber beam has a width of 6 in. Determine its height $h$ so that it simultaneously reaches its allowable bending stress $\sigma_{\text {allow }}=1.50 \mathrm{ksi}$ and an allowable shear stress of $\tau_{\text {allow }}=50$ psi. Also, what is the maximum load $P$ that the beam can then support?
