7. A bar with a square cross-section is 10mm x 10mm in widths and 100mm long is to be subjected to a tensile load of 500N. Based on the requirements below choose from the table appropriate materials for each application. Show your work and explain how you arrived at your choices. • the maximum elastic elongation on the bar due to the load must be less than 0.25 mm; Material Alumina Ceramics 4340 steel alloy 304 stainless steel Naval brass 464 2024-T3 aluminum alloy Delrin 500 E (Gpa) n 410 200 0.12 195 92 73 3 لیا 0.44 0.21 0.17 In addition to the requirements listed in (a), the bar also needs to be an electrical insulator. What would your choice be? K (MPa) 2650 1400 585 780 • What if now the conditions become that the total amount of elongation allowed is 0.5mm, and it can include some plastic deformation? Which ones would you choose now?
