How much compressive load can a round 10-inch-diameter concrete column support? The allowable unit stress is 2,000 psi.
Use the equation f=P/A where f is stress, P is load, and A is area.
Round the value of π to the nearest hundredth. Express your answer in pounds.
Incorrect - the answer is 157000
The load will be spread out over the area of the column, so we will first find the area of a 10-inch-diameter circle. Using A=πr^2, we solve for A= 3.14 x 25= 78.5 square inches.
The strength of the concrete is given to us in the question as 2,000 psi. This number is “f” in the equation f=P/A. Rearrange the given equation to solve for P.
P=fA
Now, we can just substitute in the numbers for f and A to solve for P.
P = 2000 x 78.5 = 157,000 pounds.
