Question

The marketing department is making statements that the company’s product will last ½ million cycles and is guaranteed to last. You (engineer) shake your head and walk away, muttering words not to be repeated. Now you must save the company once again. The product is made from 2014-T6 aluminum alloy and the area that is under cyclic motion (compression/tension) has a round diameter of 9-cm. The marketing VP says if it fails its your fault, so you need to determine the correct and normal loading for the product. Determine the maximum load to ensure the product surpasses the warranty period of ½ million cycles.
