2. An L-shaped gate is hinged at B as shown in the figure below. When the water level is low, the gate is kept closed and stationary. However, when water reaches the critical level h above the hinge, pressure applied to the vertical section of the gate opens the gate in the clockwise direction so that water is drained. The density of water is p, and the gate width (into the paper) is W. Note that the pressure values of air inside and outside the gate are different. (a) Draw the free body diagram, and indicate all the forces acting on the gate (including the points of action). (b) Obtain an expression for H in terms of the other variables. 이 9 2 air (2Patm) h water h A air (Patm) H
