A. (11kN.M)
My name is Ogundare Folahanmi, tel. No; +2347034849749,+971581233689.The answer is 11kN.m
6×2.5=15kNm – 2×2=4kNm then
15-4=11kNm A is correct.
MA-2*2-6*2.5=0
MA(moment about A) =19kNm
A) 11kNm
A. 11kNm
Anti-clockwise moment about B = +4 kNm
Clockwise moment about B = -15 kNm
Therefore Balancing moment = -11 kNm
Answer is (A) = 11 kN.m
11knm
A
(A) 11KNm correct option
