Aerospace Engineering Question:

The properties of the mechanics are as follows:
► Strength: this is the applied force on a material that can withstand prior to fracture. It is measured by the proof or yield stress of a material that is under action.
► Working stress: this is the stress that is being imposed on a material as a result of the load that is being subjected on the material. The loads that are given must be in the elastic range.
► Proof stress: defines the tensile stress
► Ultimate tensile stress (UTS): defines of a material that is given by a relationship or its maximum load.
► Specific strength: defines the light and strong of a material that is used in aircraft making. This is done to maximize the payload and meeting all the safety requirements.
► Malleability: defines the ability to be rolled into sheets or get a shape under pressure. This includes examples of gold, copper and lead.
► Elasticity: defines the ability of a material to return to its original shape when an external force is removed from the material.
