If the maximum force that any member can support is $8$ kN in tension and $6$ kN in compression, determine the maximum force $\backslash ($ P $\backslash )$ that can be supported at joint $\backslash ($ D $\backslash ).$

Hint: Solve for each internal force as a function of $\backslash ($ P $\backslash ),$ see which element will exceed the maximum load first, and that will tell you the max $\backslash ($ P $\backslash ).$

Ans:

$\backslash ($ P$-5\mathrm{.}20\backslash$mathrm$\{$kN$\}\backslash )$

$\backslash ($ P$-5\mathrm{.}20\backslash$mathrm$\{$kN$\}\backslash )$
