Factor of Safety means that a design uses more element than needed to compromise for unexpected cases or system failure.
In the lift system, there exists the factor of safety principle in this design, through the use of multiple metal cables (seen in Figure 8.1). This is because there are more than one metal cable used to support the lift even though 1 metal cable itself is capable to support a fully loaded lift on its own. Therefore, the multiple cables acts as a safety factor to minimize the failure of the system in case the lift is overloaded.
