9-74. The metal strap has a thickness t and width w and is subjected to a temperature gradient T, to T; (T, < T,). This causes the modulus of elasticity for the material to vary linearly from E, at the top to a smaller amount E, at the bottom. As a result, for any vertical position y, measured from the top surface, E=[(E, - E,) /wly + E. Determine the position d where the axial force P must be applied so that the bar stretches uniformly over its cross section.
