Assignment $-$ Scaffolding, Part$-2/2$

Analyze a scaffold bearer element $2"$ diameter $\frac{1}{4}"$ thick:

Use the maximum reaction load to calculate the load.

Self weight of the bearer is negligible.

Provide approximate moment deflection and shear diagrams.

Calculate the maximum moment, shear and deflection.

Assume pinned connections on each support.

Verify that actual bending and shear stress do not exceed the allowable stress. Deflection shall not exceed L$/60.$

The length of the bearing is $L=3-ft.$
