An annealed copper bar of 1.6inches length and 1 inch diameter was subjected to a tensile test. The following data points were obtained for this materialthrough careful observation and experimental stress determination methods. The engineeringstress at the onset of plastic deformation was 80,000 psi. The modulus of elasticity was 720,000 psi. The strain-hardening index was 0.5. What is the strength coefficient of the material, true yield stress, and the true ultimate stress

answer:

all three have their own beauties

explanation:

it is difficult to choose someone as most beautiful

i do not know

Explanation:

If the temperature goes on increasing with respect to the length (i.e temperature gradient)then it is called positive heat transfer. If the temperature gradient decreases then it is called negative heat transfer.

Explanation:

i'd try logging out, closing the browser, and unplugging the computer for a few seconds and then start everything back up again and log in. if it still doesn't work, maybe try clicking slower. or close a couple tabs or other windows you may have up

I don't know much ab computers but I hope this helped
