A fastener bolt for the airframe of a glider has a cross-sectional area of 1.0 square cm and a length of 4.0 cm. The part must be able withstand a tensile force of 1.0 × 104 N, and as a factor of safety this tensile force can produce a stress of no more than 50 percent of the tensile yield stress in the bolt. For damage tolerance the bolt must have at least 10 percent strain to fracture. Because weight is critical for this glider design the maximum weight possible for this bolt is 8.0 g. The bolt is not subject to high or low temperatures. Of the materials covered in this chapter what would be the best material to select? Because this is an aircraft part it not necessary to choose the cheapest material, but excessive cost should be avoided.
What will be an ideal response?
