Using the method of sections, determine the force in member BE for the loaded truss shown in Figure $2.$ Indicate if the member is in tension or compression. The truss is connected with a pin at point A and has a roller support at point F$.$

Use a sign convention that negative forces occur in compressive members. Within onQ provide the force in member BE $($use a negative if member is in compression$).$

F$1=70$ kN

F$2=40$ kN

The length of members AB$,$ BD$,$ DF are each $10\mathrm{.}0$ m$.$ The height of truss is $5$ m $($e$.$g$.,$ member BC is $5$ m in length$).$
