1. The problem statement, all variables and given/known data Calculate the magnitude of the bending moment and shear forces at the centre of the beam shown in the attached figure 2. Relevant equations 3. The attempt at a solution For the shear forces I think its the sum of the vertical components, Bending moment = not quite sure. I would appreciate if someone could give me a few pointers on bending moments and shear forces. Have looked over some textbooks but it really isn't explained well. Appreciate ANY help.
