Factor of Safety
Factor of safety use of elements of more than considered necessary to compensate for effects of unknown variables and to prevent failure. Use of elements of more than considered necessary to compensate for effects of unknown variables and to prevent a system failure. Security that is used to compensate for effects of an unknown potential this. This is adding material and components to the system to create an a design reliable than the specifications necessary to meet design requirement.
Example: The maximum capacity of a washing machine
Source: Taken from own house
Explanations:
Washing machines are designed to have different maximum capacity to support the different weight of laundry load. Based on the example given, the maximum load for the washing machine is only 8 kg. Knowing that consumers will not weigh their laundry before putting it into the washing machine, the designer of this washing machine applies factor of safety by stating the washing machine only can hold up to 8 kg although the washing machine is still functional above the wight of 8 kg.
