The wishbone construction of the power pole supports the three lines, each exerting a force of \( 4 \mathrm{kN} \) on the bracing struts. If the struts are pin connected at \( \mathrm{A}, \mathrm{B} \), and \( \mathrm{C} \), determine the resultant internal loadings at cross sections through point \( \mathrm{E} \) and point \( \mathrm{F} \).
