Define engineering failure. Give two examples of the following: a) Designing to avoid failure and b) Designing to achieve failure.

Solution

an engineered system failed when it not working properly,majority of the failure is fatigue failure and is defined as the tendency of a material to fracture by means of progressive brittle cracking under repeated cyclic stressof an intensity considerably below the normal strength.

example of to avoid the failure is machine component of rigidity criteria and strength criteria and increase factor of safety and take endurance limit

to achieve is UTM universal testing machine and rotating beam fatigue testing machine
