Consider a tie rod transmitting a tensile force F. The corresponding tensile stress is given by , where A is the area of the cross section. The deflection of the rod is given by Equation (4–3), which is , where l is the length of the rod. Using the Ashby charts of Figures 2–24 and 2–27, explore what ductile materials are best suited for a light, stiff, and strong tie rod. Hint: Consider stiffness and strength separately.
