Hey guys, So it's been a while since I've done F.B.D's, and what seems like a simple problem is causing me grief. I have this scenario below, where there are two rigid bodies, first one is ABC which pivots at fixed point B. This is connected with a pin to CDE, where D permits horizontal motion only, and where E is a wall which has stopped all rotation. The distances are only shown roughly to show you the logic i was using to try solve it. First I looked at ABC, and dedcided Fc would need to balance the external force "T", so I got Fc=25N Then I looked at CDE, and decided that Fe would need to balance Fc, and I got Fe=71.4N. But I think i've missied something, as if I sum the forces on CDE, I only have the one force in the X direction, i.e. Fe =71.4N. D cannot impose any force in the x direciton (ignoring friction), so this tells me I didn't calculate the forces at join 'C' properly. Can someone tell me what I've done wrong here? I seriously was looking at this all day and was just scratching my head. Thanks!
