Okay, kengstanley86, let's solve this one in English. Here are the calculations for part (b) of the question, using the data from Figure 4: b) Figure 4 i) The stress in the wire Stress () is defined as the force applied per unit area. Given: Force F = 100 N Wire diameter d = 0.24 mm = 0.24 × 10^-3 m Step 1: Calculate the radius of the wire. r = (d)/(2) = 0.24 × 10^-3 m2 = 0.12 × 10^-3 m Step 2: Calculate the cross-sectional area of the wire. A = r^2 A = (0.12 × 10^-3 m)^2 A = (0.0144 × 10^-6 m^2) A ≈ 4.52389 × 10^-8 m^2 Step 3: Calculate the stress. = (F)/(A) = 100 N4.52389 × 10^-8 m^2 ≈ 2.21 × 10^9 Pa The stress in the wire is 2.21 × 10^9 Pa. ii) The strain in the wire Strain () is defined as the extension per unit original length. Given: Original length L_0 = 1.76 m (from Figure 4) Extension L = 0.04 m (from Figure 4) Step 4: Calculate the strain. = ( L)/(L_0) = 0.04 m1.76 m ≈ 0.0227 The strain in the wire is 0.0227. iii) The Young's modulus of the material Young's modulus (E) is defined as the ratio of stress to strain. Step 5: Calculate Young's modulus. E = ()/() E = 2.21 × 10^9 Pa0.0227 E ≈ 9.74 × 10^10 Pa The Young's modulus of the material is 9.74 × 10^10 Pa. That's 2 down. 3 left today — send the next one.
