WebJan 21, 2024 · Length of Aluminum bar L = 125 mm. square cross section s = 16 mm. so area of cross section of the aluminum bar is; A = s² = 16² = 256 mm². Tensile load acting the bar p = 66,700 N. so. Δ = PL / AE. we substitute. 110.08E = 8337500. E = 8337500 / 110.08. E = 75740.37 MPa. Therefore, the modulus of elasticity of the aluminum is 75740.37 MPa Web2 .12 A square aluminum bar should not stretch more than l mm when it is. subjected to a tensile load. Knowing that E = 70 GPa and that the allowable tensile. strength is 120 MPa, determine (a) the maximum allowable length of the pipe, (b) the required dimensions of the cross-section if the tensile load is 28 kN. P-: z kN.)
