I was wondering if someone could have a look at my calculations. I believe I'm on the right track but I keep getting wrong answers, but I might be mixing + and - somewhere. I'm also a little unsure about the right way to incorporate the force working on top of the beam. The task reads: A combined beam ABCD is resting on a hinged support in A, and on rollers in B and D. In C there is a frictionless joint. There is an evenly distributed load q on top of the beam. Calculate Ay, B and D. 3. The attempt at a solution Due to the number of unknowns I split the beam in C and looked at the two halves independently. I've attached my calculations as a file to this post. I'd appreciate it if someone could take a look.
