A small dam is constructed across a stream. vertical cross section of the stream is y=2x^2. the dam is 4 ft tall. Set up and evaluate an integral that estimates the hydrostatic force on the damn when the water is all the way to the top. Force=Pressure*Area and Water weighs 62.5lb/cubic foot.

Best ResponseYou've already chosen the best response.0I am trying to figure out the length across the top of the dam. Well, you already have an integral on your diagram, I am trying to set up an integral from scratch.

Best ResponseYou've already chosen the best response.0This is my hail mary: integral 0 to 4, (62.5pi/9)*4x^2 dx. Let's hope we're right or anyone on the other side is going to drown.
