Telecurso 2000 - Ensaios de Materiais - 02 Ensaio de tração e cálculo da tensão

Telecurso 2000 Handout - Materials Testing: http://bmalbert.yolasite.com/resource... You have certainly ridden in an elevator, observed a load being lifted by a crane, or seen, in your company, an overhead crane transporting large loads back and forth. In addition to the large loads moved in these situations, another fact certainly catches your attention: the steel cables used in this equipment! Do you have any idea of ​​the stress these cables have to withstand when moving these loads? Do you know what this stress is called and how it is calculated? Do you know that determining this type of stress and specifying cable dimensions are among the most frequently encountered problems in the field of Mechanics? Both oversizing and undersizing of products can have serious consequences: the first because it generates waste of material, higher energy consumption and low performance; the second because the product will fail and, in addition to the loss, can cause serious accidents, with irreparable damage. These considerations serve to illustrate how important it is to know the strength of materials, which can be evaluated by performing mechanical tests. The most important mechanical test for determining the strength of materials is the tensile test. If you are interested in deepening your knowledge on these subjects, you are on the right track. In this lesson you will have the opportunity to learn about the units of measurement used in tensile mechanical tests. You will learn what is meant by stress and strain. And you will learn the formula for calculating the stress to which materials are subjected during use. Stay with us!
