Explanation of Solution

When the pollutant enter the water through a pipe or a stream at a certain point where the pollutant’s concentration is maximum, then it said to be point source of pollutants. For example, the pollutants produced in industrial activity like oil and gas extraction, mining, and manufacturing.

When the pollutants spreads out over a linear distance, then it said to be linear source of pollutants. For example, aircraft air emission, roadway air pollution.

When the pollutants spreads out over a two dimensional area, then it said to be linear source of pollutants. For example, application of pesticide over a agricultural field.

The clean water act (CWA) 1972 addresses point, line, and area sources of pollutants.

A single-angle tension member of A36 steel must resist a dead load of 35 kips and a live load of 84 kips. The length of the member is 18 feet, and it will be connected with a single line of 1- inch-diameter bolts, as shown in the figure below. There will be four or more bolts in this line. For the steel Fy = 36 ksi and F₁ = 58 ksi. Try the tension members given in the table below. Tension member rz (in.)
