Question #$2$

A specimen prepared for a tensile test has a gage length of $50$ mm and diameter of $13$ mm $.$ The

force that creates $0\mathrm{.}2$ percent offset is $66640$ N and the specimen can sustain $82320$ N as the

maximum load. Fracture of the specimen occurs at $71540$ N$.$ Knowing that the diameter of the

specimen right at the fracture point is $8$ mm and its gage length at fracture is $65$ mm ; calculate the

yield point, ultimate tensile stress, fracture stress, percent elongation and percent reduction in cross

sectional area. $($Use engineering stress and engineering strain$).$
