A 200 lb homogeneous gate of 10 ft width and 5 ft long is hinged at point A and held in place by 12 ft long brace as shown in fig. 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.
The member is supported by a pin at A aand a cable BC. If the load at AD is 300 lb, determine the x,y,z components of reaction at the pin A and the tension in cable b c
