# Tensile test elongation calculation

When objects tensile test elongation calculation put under stress, they will stretch before breaking. Knowing how an object will elongate is critical for designing machines that will operate elongatlon stressful conditions, such as airplanes and racing cars, so that they do not elongate so much that they no longer have enough strength to withstand the forces while elongated. Calculate the cross-sectional *tensile test elongation calculation* of the bar. Measure the diameter of the bar and divide it by two to get the radius. Square this number and multiply by pi. For example, if the diameter is 2 inches, divided by two to get a 1-inch radius, square it and get 1 inch squared, and multiple by pi to get 3.14 inches squared.

The results from the test are commonly used to select a material for an application, for quality control, and to predict how a material will react under other types of forces. Tensile tests are conducted to determine tensile strength, yield strength and elongation of a material. These properties depend on the alloy and temper as well as shape of the material being tested. ASTM E 8 specifies tensile testing procedures for metallic materials.

The material has known dimensions, like length and cross-sectional area. We then begin to apply weight to the material gripped at one end while the other end is fixed. We keep increasing the weight (often called the load or force) while at the same time measuring the change in length of the sample.
