Hallo all, I have been working on a little problem. I have to calculate the forces on a certain structure, but I can not seem to find the solution. I have given a picture, drawing with my attempt and the drawing of how I try to solve it. The first drawing is to find the first forces, those are easy. Then I split the structure in 2 structures to find the other forces, however when I do this I get 2 structures with 3 equations, in total 6 equations. But when you try to work those 6 calculaitions, you will see they are the same (meaning those 6 equations are only 3 equations). Any one who can help me out here? The forces 450N and 300N are given. http://img375.imageshack.us/my.php?image=teck0.jpg http://img375.imageshack.us/my.php?image=teck0.jpg The distances are in metres (drawing is not really accurate in scale:rofl:) As you can so I start of with calculating the force on A , then I find the forces in C. But then I get stuck.
