Question
100%
For the three-pinned frame shown in picture i am trying to detemine the:
1. Determine the reactions at supports A and B.
2. Draw the shear force diagram for member AC.
3. Draw the bending moment diagram for member BFE.
4. Draw the axial force diagram for member CD.
5. Determine the maximum bending moment in member AC.
Detail answer with actual calculations and drawings please for better comprehension. I have tried to attempt this question multiple times, however if seems to be incorrect. I will upvote, if answer is detailed Thank you
