Problem $9\mathrm{.}10$

For the truss shown, determine the maximum tensile axial force in member $BE$ and the maximum compressive axial force in member $BF$ due to a concentrated live load of $120$ kN $,$ a uniformly distributed live load of $40k\frac{N}{m},$ and a uniformly distributed dead load of $20k\frac{N}{m}.$
