| Answer» MODULUS for steel wire:Y1 = (F1/A1) x (L1/ΔL1) = F1 x 4.7 / 3.0 x 10⁻⁵ x ΔL ----(1) Young's modulus for COPPER Y2 = (F2/A2) x (L2 /ΔL2) = F x 3.5 / 4 x 10^-5 x ΔL----(2) By 1 and 2 Y1 / Y2 = 4.7 x 4.0 x 10^-5 / 3.0 x 10^-5 x 3.5 = 1.79 : 1 Young's modulus for steel wire:Y1 = (F1/A1) x (L1/ΔL1) = F1 x 4.7 / 3.0 x 10⁻⁵ x ΔL ----(1) Young's modulus for copper:Y2 = (F2/A2) x (L2 /ΔL2) = F x 3.5 / 4 x 10^-5 x ΔL----(2) By 1 and 2, Y1 / Y2 = 4.7 x 4.0 x 10^-5 / 3.0 x 10^-5 x 3.5 = 1.79 : 1 Keep smiling!!! | |
