Question $1$:

Draw the SFD and BMD for the beam shown in Fioure $1$

Question $2$:

Apply the principle of superposition for bending moments as described on page $19$ of Course Notes #$1$ to determine the bending moment at the mid$-$span of the cantilever beam shown in Figure $2.$ Verify the above result by using the free$-$body diagram to determine the bending moment at the mid$-$span.
