Simple moments !! Can't do !!! Urgent 1. The problem statement, all variables and given/known data Determine the reactions at the smooth collar A, the rocker B and the shortlink CD. 2. Relevant equations RC = Normal reaction at smooth collar A. RN = Normal reaction at rocker B. RD = Normal reaction at D. Moment at rocker B is given to be 4KN. All distance shown in the diagram(made in paint) are in meters. 3. The attempt at a solution The equations I made are :- Taking moments at B... (RCsin45*10) + (2.5cos60*3) + (4) = (RCcos45*3) + (RD*3) + (2.5sin60*6) Forces.... RCcos45 = RD + 2.5cos60 RCsin45 + RN = 2.5sin60 The answer I get is wrong after calculating. Where does the error lie?
