Give the reason of following:1. Tensile strength of metals2. Lusture of metals |
|
Answer» 1)it is important becauseIt is a quick way to detect problems in the material that you are purchasing. It measures tensile strength. If your design needs a certain material tensile strength, you will know if this material will work for you. You can get tensile modulus out of the test results. This can go into your design equations to see if the material will work for you. You can get Poisson's Ratio, which is important for use in finite element analysis. that's wrong and also I want the answer of 2nd one 2)It has to do with the way light and electrons on the surface ofmetals interact. ...Metalis shiniest when it is first cut. Exposure to elements such as oxygen and carbon causemetalsto lose thelusteron the surface because the elements cause a tarnish that reduces the freedom of the electrons to vibrate. |
