1.	In tension test, the elongation or strain in the elastic region of material can be measured with the help of extensometer.(a) True(b) FalseThe question was asked by my college director while I was bunking the class.Query is from Testing of Mechanical Properties in portion Inspection Testing in Foundries of Casting-Forming-Welding I
Answer» CORRECT option is (B) False The explanation: The load in the specimen can be read DIRECTLY from the TESTING machine, while the elongation is measured with the help of extensometer. But in the elastic REGION, the strains are so small that cannot be measured by extensometer, so some type of magnification of the deformations are generally required to measure the strains.
