1.A foot ball field(120x180) yards measures 1.08x0.72 inches on a photo. what is the scale of the photo? what would the field measure on the photo(in inches) if the field were on a plateau 600 feet above the general ground elevation.
2.A natural channel that is clean and irregular(n= 0.040) has a bottom width of 15 ft m, side slopes of 6:1 (H:V) and a bottom slope of 0.0002. Using Manning's equation, determine the normal depth in the channel for a discharge of 720 cfs.
3.If you have 10 kips acting downward on a foundation and footing, 4 feet long, with uniformly distributed load acting up ward of 2.5 k/ft (soil) also 4 ft long. what are the reactions, shear forces, and bending moments at the tree critical points?
