Could someone please explain to me what it means (in terms of forces acting) 'freely jointed' and 'freely hinged'? Or is it the same thing? I'm really confused, I have my mechanics exam coming up soon ( A levels mechanics) and not sure how to deal with these questions. I understand that if there's a hinge, there are also two reactions (at 90 degrees to each other) but what happens when two beams are 'freely jointed' to each other? e.g a horizontal beam (made from part A and art B) is hinged to the wall and is in equilibrium. Part B of the beam is freely jointed at the end of part A. so what does this mean in terms of forces acting at this point?? would be very grateful for any response and explanation :)
