1.A trapezoidal canal of side slopes 1V : 2H, and having n = 0.017 is to carry a uniform flow 37 m^3/s on a slope of 0.0005 at a depth of 1.5 m. Calculate the base width of channel ?
2.The ladder AB weighs 10 N and leans against a wall as shown. Assuming that the coefficient of static friction µs is the same at A and B, determine the smallest value of µs for which equilibrium is maintained. The weight force acts at the center of the length of the ladder.
