[QUOTE="SteamKing, post: 5475093, member: 301881"] You need to lay out what the individual parts of the expression are telling you. I think you are just confused seeing several parts rolled up into one expression. You have correctly discerned that (10/2) comes from applying symmetry to the frame. What force is given by the expression 5 / cos (30°) ? [/QUOTE]
