1. The problem statement, all variables and given/known data The body is connected to the ground with a moving joint at B, the body slides with no friction at A. 2. Relevant equations ΣF=0 => ΣFx=0 & ΣFy=0 ΣM=0 3. The attempt at a solution First I made a drawing: At this point I started calculating: ΣFx=>P-R2-F1, so: P=R2+F1 ΣFy=> R1+F2-mg=0, so: R1+F2=mg I'm quite confused when it comes to the moment around B, I know that Moment=force*distance, but how do I draw all the distance that I need? I thought about something like that: So, the distance between F1 and the point B is a, while the distance between F2 and B is b. Knowing this, I assume that the moment would look like that: Mb: P+mg-F2*b-F1*a-R2-R1=0 now I replace P and mg according to the previous equations: Mb: R2+F1+R1+F2-F2*b-F1*a-R2-R1=0 now the weird part is that I could reduce almost everything in the equation above, so that I would only be left with: Mb: b-a=0 but it doesn't make any sense. I would appreciate any help, thank you in advance!
