simply supported with loading and support conditions given below.

A$-$D beam

Its cross$-$section is as stretched in section a$-$a$.$

Given loading conditions

maximum

formed at point a specified in the upper right corner of the section under the effect of the bending moment.

What is the magnitude of the stress in MPa? $($Note: dashed line shown on section a$-$a

It represents approximately the horizontal and vertical axes passing through the center of gravity.

First, determine the location of the center of gravity of the fraction.
