We have to first determine the slopes of GH and BG which are for GH is 2H:1V and for BG is 2H:3V. HS 2 Im BG √√13 2m 2 Анод BC B 2m- Av=15kW 10KW 9 Step 3: Solve for the forces required, BC,BG and GH *To determine BC we take summation of moment forces along G so that the other two unknowns BG and GH will be canceled G because their paths go to point
