1.A line of slope 4:10 has been scribed on a coldprolled yellow-brass plate, 6 in. wide and 1/4 in. thick. Using the data available in Appendix B, determine the slope of the line when the plate is subjected as shown to a 45-kip centric axial load.
2.It rains 3.0 in. on a 20.0 acre watershed. What is the volume of rainfall excess if 30% of the watershed area is a lake and infiltration on the soil is estimated at 1.0 in? What is the total volume of runoff? Express your answer in cubic feet. Assume that the lake level is low and does not contribute to rainfall excess. Hint: Lakes are treated as initial abstraction.
