SOLVE ONLY $16\mathrm{.}13$ PLEASE:

An offset link has dimensions and loads as shown. For

cross section B$-$B$,($a$)$ find the maximum tensile and

compressive stress, and $($b$)$ plot the distribution of

normal stress.

$16\mathrm{.}13$ Solve Prob. $16\mathrm{.}12$ with cross section B$-$B modified as

shown in the figure.
