Steel such as this is no longer used very much in reinforced concrete. It is included here for you to compare the behaviour of mild steel with high-tensile steel.The sample in this test is held between two jaws. The testing apparatus pulls the upper jaw upwards, causing the sample to stretch until it breaks.Reinforcing steel is used in reinforced concrete elements to give these elements tensile strength.At the end of the video a graph of vertical load versus vertical deflection shows how mild steel behaves under tension.

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. Tensile TestOne can do a very simplified test at.
