$($A$)$ Determine internal shear force and bending moment for beam below by using $2$ th order method or $4$ th order method. Calculate slope and deflection functions for each segment.

$($B$)$ Determine the locations and values of maximum tensile flexural stress and maximum compressive flexural stress. Describe the locations using coordinates in $x$ and $y.$

Use $E=70$GPa.
