For the truss of Problem 8.50, 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 40 kN/m, and a uniformly distributed dead load of 20 kN/m.

Reference: Problem 8.50

Draw the influence lines for the forces in the members identified by an ‘‘×’’ of the trusses shown in Figs. P8.45–P8.52. Live loads are transmitted to the bottom chords of the trusses.
