Problem $2$:

The steel beam $\backslash ($ A B C D $\backslash )$ shown is supported at $\backslash ($ A $\backslash )$ and by two steel cables with a diameter of $0\mathrm{.}5$ in $.$ at $\backslash ($ B $\backslash )$ and $\backslash ($ D $\backslash ).$ The second area moment of the beam is $\backslash ($ I$=1\mathrm{.}2\backslash$mathrm$\{$in$\}^\{4\}\backslash ).$ A force of $5$ kips is applied at point $\backslash ($ C $\backslash ).$ Using the singularity function method, determine the stresses in the cables and the deflections of $\backslash ($ B$,$ C $\backslash ),$ and $\backslash ($ D $\backslash ).$ Note: You have to use the axial deflection equation $($Young$\text{'}$s fourth equation$)$ to solve this problem.
