A dam is made which is rectangular and flat in profile. It is a depth of 25m and a width of 100m and holds back fresh water which has a density of 1000 kg m3 . Hint: You will need to express the force as a function of vertical position, and then integrate over the possible values of vertical position. (a) What is the total force that the water exerts on the dam? (b) What is the total torque that the water exerts on the dam measured around the dam’s bottom?

Force on a Dam Wall (Mastering Physics)
As the reservoir behind a dam is filled with water, the pressurethat the water exerts on the dam increases. Eventually, the forceon the dam becomes substantial, and itcould cause the dam tocollapse. There are two significant issues to be considered: First,the base of the dam should be able to withstand the pressure, where is the density of the water behind thedam, is its depth, and is the magnitude of the acceleration due togravity. This means that the material of which...
