1. The problem statement, all variables and given/known data The special tool is used for installing and removing snap rings.Determine the spreding force applied at G and H if P=50N. 2. Relevant equations ƩF_x=0 ; ƩF_y=0; Ʃm=0 3. The attempt at a solution I am drawing the FBD of the A-C-F-H part of the special tools. I have at A(the 50-Ns of 5) ,at C I have the reaction from the two force member CD , at F I have two Fx and Fy from the pin , and at H I have the H force in the negative y-direction.So I have 4 unkowns and three reactions, where is my mistake or what should I do, in order to get the right result?
