Why modulus of elasticity is important

Furthermore, with increasing temperature, the modulus of elasticity diminishes. Subscribe to our newsletter to get expert advice and top insights on corrosion science, mitigation and prevention.

Young's modulus is given by the gradient of the line in a stress-strain plot. So a fiducial marker such as some tape can be used to help identify the original and extended lengths.

Making multiple measurements with a variety of masses will increase the number of points on the stress-strain plot and make the calculation of Young's modulus more reliable. Another thing to take care of is measuring the cross-sectional area of the wire. Imperfections of the wire may mean that the diameter is not perfectly constant along its length, so taking the mean of several readings with the micrometer could help.

Studying of the mechanical properties of materials is important because it helps us understand how materials behave, and allows us to develop new products and improve existing ones.

One example research topic at Birmingham looked at developing vaulting poles used by high jump athletes to maximise performance. These poles need to be light to allow a fast run-up, but also must be able to store elastic strain energy as the pole bends. The pole has to convert elastic energy to kinetic energy as the pole straightens out, and be able to withstand the stress caused by the weight of the vaulter - and withstand repeated uses by the athlete. A good analogy to this would be a rubber band: when you stretch a rubber band you are not deforming it, but stretching it.

However, if you pull it too hard the rubber band will begin to deteriorate, or deform. Usually when this happens, it is not too much longer until it breaks. The Young's Modulus is very important to doctors and scientists as this constant can tell them when a structural implant will deform.
