5.) Two previously undeformed specimens of the same metal are to be plastically deformed by reducing their cross-sectional areas. One has a circular cross section, and the other is rectangular; during deformation the circular cross section is to remain circular, and the rectangular is to remain as such. Their original and deformed dimensions are as follows: Circular Rectangular (diameter, mm) (тm) Original dimensions Deformed dimensions 18.0 20 x 50 15.9 13.7 x 55.1 Which of these specimens will be the hardest after the plastic deformation? a) The deformed circular specimen will be harder b) The deformed rectangular specimen will be harder c) Both will have the same hardness d) Both would brake e) No estimation can be made for such process

Hi, I need help with this question.

will downvote if wrong

clearly explain the terms linear strain and shear strain,what do they measure,how are they different ?use diagrams to explain the answer

Part D-Permanent elongation of the specimen if the specimen is loaded until its nominal stress value reaches 65 ksi, determine the increase in gauge longth after it is unloaded. The strain at 65 ksi is 06 in. /in.
