1.	Which of the following stresses is takes place during performing the wire drawing operation?(a) Tensile stress(b) Bending stress(c) Indirect compressive stress(d) Shear stressI had been asked this question in unit test.Enquiry is from Classification of Metal Forming Processes topic in division Forming Process of Casting-Forming-Welding II
Answer» Correct answer is (c) INDIRECT compressive stress The explanation is: WIRE drawing is a forming process in which a round metallic bar is pulled by a machine by generating indirect compressive stresses in the bar. This causes thinning of bar and results in the FORMATION of thin wires that further used as a cable or for ELECTRICITY PURPOSES. Wire drawing is most suitable for ductile materials.
