Unformatted text preview: production run of 105106 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 shapeefficiency 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 sectionshape to maximize the quantity: where σ f is the failure stress and ρ the density of the material of the beam, and is the shapeefficiency factor for failure in bending. 3 f B ϕ f B Figure 3...
