The compressive stress is [tex]500Ib/in^2[/tex]

The formula that is used for calculating compressive stress is expressed as;

Stress = Load/Area

The area of the concrete cylinder can be calculated as area of a circle written as;

Area = πr²

Where r is the radius and π takes the constant value of 3.14

From the information given, we have that the diameter of the cylinder is 6

but diameter = 2 radius

then, we get;

Radius = 3 inches.

Substitute the value, we get;

Area = π × 3²

Find the square

Area = 28. 26 square inches

Compressive stress = Load/Area

= 141,300 / 28. 26

Divide the value

= [tex]500Ib/in^2[/tex]
