Find the internal forces at point $\backslash ($ J $\backslash )$ which is located $0\mathrm{.}6$ ft from the roller, given $\backslash ($ a$=1\mathrm{.}2\backslash$mathrm$\{$ft$\}\backslash )$ and $\backslash ($ b$=0\mathrm{.}7\backslash$mathrm$\{$ft$\}\backslash )$ when the load $\backslash ($ P $\backslash )$ is $2\mathrm{.}3$ klips $.$

Using the left potion of the member the internal loads at J are
