Hello!!

The answer is given below.

72 0 cos section Cross Section :- a K 3211 taul , 181. Cross Sectional area → A,= 72x6 = 432 si = 3 st A2 = A3 = 11 x 3226=9SFX = 23625 - 1575** @A, *=0 - SFA = 236256 @B, x= 30ft SFB= - 2362516 @SEx=0 23625 = 1575xx + x = 1.5x 10 = 15 ft BMx = 2362(15751b/ft momma B - 2362516 - RA+ Re= 1515430 It is symmetrical loading - KA = Ra RA= RB= 1575830 SFD → - 2 2362516 177187.5
