1. A freshwater marsh is drained to the ocean through an automatic tide gate which is 6 ft high. The gate is held by hinges located along its top edge at A and bears on a sill at B. At the given time, the water level in the marsh is right at the hinge (h = 6 ft) and in the ocean d = 9 ft. Determine the force exerted by the sill on the gate at B. (Specific weight of fresh water = 62.4 lb/ft³; of salt water = 64 lb/ft³.) 2. Determine the force in each member of the truss whichever method you prefer. 100 ib Marsh h = 6 ft 200 lb 14 10² * 10' Ocean d = 9ft 30° *10' 161
