1.A 6ft wide, 10ft high vertical rectangular gate has its top edge 6ft below the water level. it is hinged along its lower edge. what force, acting on the top edge, is necessary to hold the gate shut?

2.Two vertical forces are applied to a beam of the cross section shown. Determine the maximum tensile and compressive stresses in portion BC of the beam.

3.Base course aggregate has a target dry density of 119.7 lb/cu ft in place. It will be laid down and compacted in rectangular street repair area of 2000 ft X 48 ft X 6 in. The aggregate in the stockpile contains 3.1 percent moisture. If the required compaction is 95 percent of the target, how many tons of aggregate will be needed?
