# How to Calculate Elongation?

Calculating enlongation can be scary to look at, but it is actually quite simple. Let's assume we're finding the elongation of a bar. First, measure it lengthwise. Write down this measurement. You must now get the cross sectional area of your bar. Take the diameter of the bar, half it, square that, and multiply by pi. You must now look up the material your bar is made out of and determine its elasticity in pounds of force per square inch. Once you have all this information down, determine the amount of pounds of force will be exerted on your bar. Plug all this information into the elongation equation and solve.
