Factor of safety

In engineering, a factor of safety (FoS), also known as (and used interchangeably with) safety factor (SF), expresses how much stronger a system is than it needs to be for an intended load. Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy. Many systems are intentionally built much stronger than needed for normal usage to allow for emergency situations, unexpected loads, misuse, or degradation (reliability). (Wikipedia).

Thermal conductivity fundamentals

Thermal conductivity is the constant of proportionality for heat transfer in response to a temperature gradient. Thermal conductivity can be accomplished by contributions from electrons, phonons, radiation, and convection. Metals have high thermal conduction due to the many free electrons,
