Document Summary

Depanment name & course number: mechanical & aerospace engineering. Students must count the number of pages in this examination question paper before beginning to write, and report any discrepancy. This examination question paper may not be taken from the examination room. to a proctor. An engineer is faced with the following problem. His company has been manufacturing a component, which has a part in the shape of a large plate, using a titanium-aluminum alloy. This alloy has a yield strength of 900 mpa and a fracture toughness of. It has been suggested to him that a weight reduction could be obtained if the alloy was in its. However, in this condition the toughness reduces to. The design requirements for this component states that a critical edge crack in the plate be larger than the minimum detectable crack size of 5 mrn. In addition the design stress is specified to be equal to or less than 50% of the yield stress.
