Data: P = 332N Which option is right? a) if the plate had a weight of 332N (applied vertically downwards in the center of the plate), the reaction Dy on the plate should be vertical downwards so that the plate still remained in balance in that position or b) if the plate had a weight of 332N (applied vertically downwards in the center of the plate), the reaction Dy on the plate should be vertical downwards so that the plate still remained in balance in that position
