1. The problem statement, all variables and given/known data The plate has a dimension of 460mm X 260mm, subjected to a central load of 400N. Determine the reaction A and B, each representing a roller support as a wheel, located at the center of one edge. (opposite blue arrows have the same resultant value.) Are they the same ? If not how can I find them out ? 2. Relevant equations N/A 3. The attempt at a solution I did both force and moment summation giving me A+B=200. I am sorry if this seems like a kindergarten problem.
