Make sure that al individual unit functions are identified, and part geometry and material are configured, which will ultimately lead to final product configuration. (Group work) 1) 2) Figure 1 (see next page) shows the top and down tubes of a bicycle frame. Determine a combination of material properties, which can either be maximized or minimized, if the customer Individual work) a) Wants to have a minimum mass frame with high strength. The constraint is the outer diameter of the tube (i.e. the outer diameter of the tube cannot be changed). The function of the tube is to carry bending load b) Wants to have a minimum mass frame with high stiffness. The constraint is the same as in (a) but the function of the tube is to carry torsional load. Solve (a), if the constraint is the ratio of outer diameter to wall thickness of the tube c) Tools Mobile View Share
