A cantilever timber beam $($FIGURE A$)$ with a span of $L=13\mathrm{.}9$ fi supports a linearly distributed load with maximum intensity of $w_0.$ The beam with is $b=1600$ in and the beam height is $h=8\mathrm{.}75$ in$.($Figure $B).$ The allowable bending stress of the wood is $1200$ psi. Calculate the magnitude of the maximum load $w_0$ that may be carried by the beam.

$$

Incorrect. In this case, the location of the maximum magnitude bending moment can be determined by inspection it occurs at support A$.$ To confirm this, construct a shear$-$force and bending$-$moment diagram. The maximum magnitude Internal moment equals the magnitude of the reaction moment at $A.$ Determine the reaction moment $A$ in terms of $w_3$ by summing moments about $A.$wo lb:fteTextbook and MediaAssistance UsedefextbookHintAssistance UsedSavefor Later Last saved $1$ second ago.Attempts: $2$ of SusedSaved work will be auto$-$subuitted on the dur date.
