Structville daily questions
From now henceforth, Structville will be publishing daily questions on different aspects of civil engineering. You are expected to enter your response in the comment section. At the end of every week, exceptional participants will stand a chance to win some gifts. This exercise is open to participants all over the world.

Today's Question
For the  frame loaded as shown above, which of the options is the most likely bending moment diagram considering linear elastic response.

Thank you for participating in exercise today, remember to enter your answer in the comment section. The main aim of this exercise to stimulate knowledge of structural analysis on the internet in a fun and exciting way. We are always happy to hear from you, so kindly let us know how you feel about Structville.

1. 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

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
