The Thénard shutter dam shown was originally developed and used in 1831. Assume frictionless hinges at B and C and neglect the weight of the dam. Calculate the reactions at C and D, assuming a 1-ft width of dam (perpendicular to the page). Note that the force of the water acts perpendicular to the surface of the dam.
