Answer
The factor of safety (FoS) is defined as the ratio of the maximum load a structure can withstand to the actual load applied. This measure ensures that structures are designed with a margin of safety against failure.

Answer
For example, if a load of 10 kN is applied to a structure that has a maximum capacity of withstanding 30 kN, the factor of safety can be calculated using the formula:
FoS=Applied LoadMaximum Capacity=10 kN30 kN=3
Thus, the factor of safety is 3, indicating that the structure can handle three times the actual load.
