4. A drainage ditch alongside a highway with a 4% grade has a rectangular cross section of depth 4 ft and width 9 ft, and – to prevent soil erosion - is fully packed with rock fragments of effective diameter 6 in., sphericity 0.7 and porosity 0.48. During a rainstorm, what is the maximum capacity of the ditch (gpm) if the water just reaches the top of the ditch?

A wood bar is subjected to tensile force of 60 kips at two ends. It is 5 ft long, and has the rectangular Cross section which height is 4 in, and width is 2 in.
(a) A wood bar is subjected to tensile force of 60 kips at two ends. It is 5 ft long, and has the rectangular Cross section which height is 4 in, and width is 2 in. The modulus of elasticity is 1.9×103ksi. Determine the total clastic deformation of the wood bar. Answer in the unit of inches, to 0.001. Note: 1 ft = 12 in., 1 ksi = 1000 psi. (b) If this wood bar has a hole with a diameter...
