Question: problem 1 a composite bar is made of two copper...

Question details

Problem 1 A composite bar is made of two copper sections Cwith cross sectional area Ac 1300 mm2 and a steel section S with cross sectional Area A,-650 mm Assuming that the moduli of elasticity for the copper and the steel are E-110 GPa and E, 205 GPa, respectively, calculate the magnitude of the tensile force P necessary to produce a total elongation δ = 1.3 mm. 150 mm 300 mm 600 mm
