Unformatted text preview: production run of 105-106 is envisaged. 1. List the function and constraints, leave the objective blank and enter choice of process for the free variable. 2. Use the charts of Chapter 7 to identify possible processes to make the casting Exercise E3 Use charts to select a joining process to meet the following requirements. 2 Figure 2: Ceramic Tap valve Exercise E4 (a), (b) and (c) Determine the shape-efficiency factor for strength limited design in bending, for the following three sections shown in Figure 3. (d) A beam of length L , loaded in bending, must support a specified bending moment M without failing and be as light as possible. Show that to minimize the mass of the beam per unit length, m/L , one should select a material and a section-shape to maximize the quantity: where f is the failure stress and the density of the material of the beam, and is the shape-efficiency factor for failure in bending. 3 f B f B Figure 3...
