Problem 3 (25 Points) The small dam shown in the figure below is 8.5 m wide. An equilateral triangular gate (LM) that is 2.4-m in height is located along the lower face (KN) so that the apex is at M. Depth of water above the hinge (L) is 4.5 m. Calculate the magnitude and point of application of the force acting on side LM. Note: For an equilateral triangle, area = A Height from any side ish- 4.5 m 24
