Problem # 1 (a) A specimen of copper having a rectangular cross section 15.2 mm x 19.1 mm is pulled in tension with 44,500 N force, producing only elastic deformation. Calculate the resulting strain. The elastic modulus for Cu is 110 x 10° N/m². (2.5 marks) (b) An aluminum bar 125 mm long and having a square cross section 16.5 mm on an edge is pulled in tension with a load of 66,700 N and experiences an elongation of 0.43 mm. Assuming that the deformation is entirely elastic, calculate the modulus of elasticity of the aluminum. (2.5 marks) (c) Consider a cylindrical nickel wire 2.0 mm in diameter and 3 × 104 mm long. Calculate its elongation when a load of 300 N is applied. Assume that the deformation is totally elastic. The elastic modulus for Ni is 207 x 10° N/m². (2.5 marks) (d) A cylindrical rod of steel (E = 207 GPa) having a yield strength of 310 MPa is to be subjected to a load of 11,100 N. If the length of the rod is 500 mm, what must be the diameter to allow an elongation of 0.38 mm? Assume that the deformation is totally elastic.
