Plot the N$,$V$,$ and M diagrams for the beam.

If the cross sectional area of the beam is a rectangle with height $=4$ times the width, what

should be the dimensions of the beam so that the axial stress does not exceed $10$ MPa at any

point of the beam? Use these dimensions for the rest of the assignment.

Plot the maximum axial stress as a function of the length of the beam.

For the location with the maximum axial stress, plot the axial stress as a function of the vertical

distance from the neutral plane.

Make a plot of the maximum shear stress as a function of the length of the beam.

For the location with the highest shear stress, make a plot of the shear stress vs$.$ distance from

the neutral axis.
