A 20mm-diameter bar of this alloy is used as a structural member in an engineering design.  The unstressed length of the bar is precisely 1m.  The structural load on the bar is 1.2×10^5N in tension.  What will be the length of the bar under this structural load (in meters)? Values from table: E [GPa (psi)] = 200(29*10^6)

Question

Consider the 1040 carbon steel listed in the textbook's Table 6.1:

A 20mm-diameter bar of this alloy is used as a structural member in an engineering design.  The unstressed length of the bar is precisely 1m.  The structural load on the bar is 1.2×10^5N in tension. 

What will be the length of the bar under this structural load (in meters)?

Values from table:

E [GPa (psi)] = 200(29*10^6)

Y.S [MPa (ksi)] = 600(87)

T.S [MPa (ksi)] = 750(109)

Percent Elongation at failure = 17
