Two cylindrical rods, one stainless steel and the other annealed copper, are joined end to end. Each rod is 1.00 m long and 1.50 cm in diameter. The combination is subjected to a tensile force with magnitude 4000 N. For each rod, what is the elongation? Ysteel = 2.0 x 1011 Pa, Ycopper = 1.1 x 1011 Pa
a) For steel, 1.6 x 10m ; for copper, 8.3 x 10m
b) For steel, 2.1 x 10 m; for copper, 1.1 x 10 m
c) For steel, 1.1 x 10 m; for copper, 2.1x 10m
d) For steel, 8.3 x 10m; for copper, 1.6 x 10m
