1.	In testing materials, only un-notched specimen of standard shape and size can be used.(a) True(b) FalseThe question was asked in an internship interview.Enquiry is from Testing of Mechanical Properties in division Inspection Testing in Foundries of Casting-Forming-Welding I
Answer» The correct answer is (b) False To explain I WOULD say: The SIMPLEST test specimens are smooth and un-notched, but more complex geometries can be USED to produce conditions resembling those in actual engineering components. Notches like holes, slots or grooves that have defined radius can be MACHINED in specimens. This gives more accurate information about the material.
