14. (6 points) A composite rod with the same cross-sectional area over its entire length is composed of materiali = "malleable cast iron" (segments AB and CD) and an unknown material (segment BC). Under the axial compressive loading shown, the change in length from point A to D is 8 = -8.46475 x 10-4.in . The material that segment BC is most likely composed of is: Consider compressive forces negative and tensile forces positive -LAB ->K LBC > Led F B A L AB = 4.5. in LBC = 2.6.in = LCD = 4.5. in "A" "annealed titanium alloy" F = 180-1bf d = 0.38 in "B" "annealed invar" "C" "malleable cast iron" "D" "0.2% Chardened steel" Choices = "E" "annealed red brass" "F" "wrought, hot-rolled monel" "G" "2014-14 wrought aluminum" "H" "structural steel" "I" "wrought iron"
