1.	The yield point of a material does not exist for those materials that have a _____________ region in that space of the stress-strain curve.(a) smooth(b) shift(c) turbulent(d) highThis question was posed to me in homework.My question comes from Aircraft Materials topic in chapter Testing Aircraft Materials of Aerospace Materials & Processes
Answer» The correct answer is (a) smooth Easiest explanation: The materials that have a SHARP break in the yield point of the stress-strain curve tend to have a yield point. These are materials LIKE WROUGHT IRON. Other materials have a smooth REGION in the place of the sharp break of yield point, hence do not have this property.
