Question: The section modulus is 4 8 in 3 . The most economical S - shape beam is S 1 5 x 4 2 . 9

The section modulus is 48 in3.
The most economical S-shape beam is
S15 x 42.9
Consider the loading shown. The allowable normal stress for the steel used is 24 ksi.
For the selected design, determine the actual value of \sigma m in the beam. (Round the final answer to two decimal places. You must provide an answer before moving to the next part.)
The actual value of \sigma m in the beam is
ksi.
