A carbon steel alloy (E= 30´10 6 psi) specimen is undergoing a tensile test. The initial gauge length of the specimen is 1 inch and the initial cross-sectional area is 0.25 in2 . When the specimen is stretched to an engineering strain of 0.09, an 80 ksi engineering stress is found. (a) What were the load and the change in gauge length values that were used to calculate the engineering stress and strain, respectively? (b) What are values of the true stress and the true strain? (c) Consider the true strain at this value of true stress. What portion of it is elastic and thus recovered upon unloading, and what portion of it is plastic?

i think its 100.

hope this !

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
