Example of Steel lab test
In a tensile test of mild steel specimen, usually a round or flat bar is gradually pulled in a testing machine until it breaks. 
• Two points, called gauge points, are marked on the central portion. The distance between these points, before the application of the load, is called gauge length of the specimen. 
• The Load is applied gradually and at regular interval of loads extension is measured. 
• The strains corresponding to the recorded extensions are calculated by dividing the extensions by the gauge length, while the stresses are calculated by dividing the loads by the original area of cross-section of the specimen. 
• Stresses so arrived at is called nominal stress to distinguish it from actual stress which is obtained by dividing the load at a particular instant by the area of the cross-section at that instant
