Question

problem #4 a tensile test of the metal specimen was performed in the laboratory but only the maximum load was measured during the test (it was 59 kn). all other data were taken before and after the test and were as follows:
a.initial diameter 13.0 mm
b.minimum diameter after the test (at a point of fracture) 10.0 mm
c.maximum diameter after test (away from fracture) 11.6 mm using this information, find the following: • the strain hardening exponent, n, for this metal • the load on the specimen at the instant just prior to fracture

Answer 1

this is a very big question but I like this question. Mai half hi iska jabab duga
