A) is the correct option.
Sum Y force= 1kN + Ra = 0 then Ra= – 1kN
Sum M(a) = 1 x (8+3) – Ma= 0 then Ma= 11kNm
A)
(A)
A
Moment@C, Mc = 1kN x 3m = 3 kNm
External Force 1kN is parallel to member BC, therefore no additional moments, Mc = Mb = 3 kNm
Moment@A, Ma = 3 kNm + (1 kNx 8m) = 11 kNm
Answer is (A)
