A sample of water contains 0.050 grams of arsenic (As) in 4.0 liters of water. Calculate the concentration of arsenic in the water in parts per million (ppm).

A simply supported beam with dimensions of b = 12 in., h = 24 in., d = 21.5 in., and L = 21 ft supports a uniform service (unfactored) dead load consisting of its own weight plus 1.7 kips/ft and a uniform service (unfactored) live load of 1.5 kips/ft. The concrete is normal-weight concrete. Determine the moment due to the factored loads, Mu.
