. Free body diagram! Find the Force in member BE Reaction forces! F1 = 4kn F-11 KN {fx=0 AF . Fit2Fzt RAx=0 Co do 24.5 Rex -4

using method of Section: 45 y Efatto =) Fitfe -f cos 45 EB Co 545 FER= 4+11 kni, . [foni tee = 91.21 KN) Any Tension .

Thefore the force on the member BE is 21.21KN tension.

I hope it helps if you like it please rate it positive or else if you have any queries regarding this please let me know in the comment section below.

Thank you

Have a great day.
