5. A platform is suspended by two parallel rods, as shown in the sketch, with each rod being 1.28 cm in diameter. Rod A is manufactured from 4340 steel (Q+T 650 °C) (E= 210 MPa, o.2 = 855 MPa); rod B is made from 7075-T6 aluminium alloy (E= 70 GPa, oo.2 = 505 MPa). a) Develop an equation giving the realtionship between the applied force and the elastic strain in the rods up to the point of yielding. Assume full elastic behaviour up to the yield strength given above and that the loading is such that the elastic strain in each rod will be the same.
