A 200lb homogeneous gate of 10ft width and 5ft length is hinged at point A and held in place by 12ft long brace as the bottom of the brace is moved to the right the water level remains at the top of the gate. the line of action of the force that the brace exerts on the gate is along the brace.
(a) plot the magnitude of the force exerted on the gate by the brace as a function of the angle of the gate, theta for 0<= theta<= 90
(b) repeat the calculation for the case in which the weight of the gate is negligible. comment on the results as theta->0
