There is an upper limit to the mechanical strength of any material under any particular test conditions. This limit is known as the ideal strength. The present paper attempts to define the ideal strength as closely as is presently possible. To this end a brief account is first given of some of the highest strengths recorded experimentally.

Oct 20 2012 · Factor of safety (FoS) also known as safety factor (SF) is a term describing the structural capacity of a system beyond the expected loads or actual loads.Essentially how much stronger the system is than it usually 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
