Question: A brass bar (E = 100 GPa) with a square cross section is subjected to axial force having a resultant P acting at distance e

A brass bar (E = 100 GPa) with a square cross section is subjected to axial force having a resultant P acting at distance e from the center (see figure). The bar is pin supported at the ends and is 0.6 m in length. The side dimension b of the bar is 30 mm and the eccentricity e of the load is 10 mm.
If the allowable stress in the brass is 150 MPa, what is the allowable axial force Pallow?
