Extracted text: Question 3: a. A mass of (Z + 50) kg is hung on a steel wire of diameter (Z + 5) mm and the extension found is (Z + 10) mm. If the Young's Modulus of the wire is 200 GPa, Calculate, i. the cross-sectional area of the fishing rope ii. the tensile strain b. A copper sheet of (Z + 75) cm width, (Z + 100) cm height, and (Z + 0.5) cm thick is acted by a shearing force of 50 × 10³ N, as shown in figure below. If the shearing Modulus of Copper is 4.2 x 101°N/m², find the followings: i. Shear Stress ii. Linear Displacement (Ax) Z=62 F Ax thick Width height
