26.5 FACTOR OF SAFETY
À
p
When we do basic design work we typically use a process of the basic format,
In particular the design process often involves a factor of safety that allows for,
- variations in material properties
- variations in expectations load
- the non-uniform distribution of stress
The factor of safety is applied as,
The values vary for various systems. The values given below are reasonable for static systems.
For example let us consider a two member mechanism 1.44 from [Beer and Johnston]
