Current Attempt in Progress

A WT$23026$ standard steel shape is used to support the loads shown on the beam in the figure. The dimensions from the top and

bottom of the shape to the centroidal axis are shown on the sketch of the cross section. Assume $L_{AB}=3m,L_{BC}=1m,w_{AB}=24k\frac{N}{m},$

$w_{BC}=10k\frac{N}{m},P_C=5kN.$ Consider the entire $4-$m length of the beam and determine

$($a$)$ the maximum tension bending stress $($a positive number$)$ at any location along the beam, and

$($b$)$ the maximum compression bending stress $($a negative number$)$ at any location along the beam.

Answers:

$($a$){}_{T,\text{m}\text{a}\text{x}}=$

$($b$){}_{C,\text{m}\text{a}\text{x}}=$
