$q=100(\frac{N}{m})P=300(N)M_0=600(N-m)L_1=6mm,L_2=2mm,L_3=2mm.$

Take $q=100\frac{N}{m},P=300N,$ and $M_0=600N-m.$

$($Take the lengths to be $L_1=6m,L_2=2m,$ and $L_3=2m.)$

$($a$)$ Draw the shear force and bending moment diagrams for the bean shown $n$ the figure.

$($b$)$ Specify the maximum positive and negative shear force and bending moment.
