The cantilever bracket is bolted to a column with three M12x1.75 ISO 5.8 bolts. The bracket is made from AISI 1020 hot-rolled steel. Find the factors of safety for the following failure modes: shear of bolts, bearing of bolts, bearing of bracket, and bending of bracket. Zim
The ability of a system's structural capability to be viable beyond its projected or actual loads is referred to as its factor of safety (FoS). An FoS can be defined as a ratio that compares absolute strength to actual applied load, or it can be expressed as a constant value that a structure must meet or surpass according to legislation, specification, contract, or standard.
Design and engineering standards often define the permitted stress, or ultimate strength, of a certain material divided by the factor of safety, rather than using an arbitrary safety factor, because these factors may be deceptive and have been found to imply more safety than is the case.
The safety factor of a product is determined by its materials and intended use. Various industries have different notions about what FoS should be required. Although there is considerable uncertainty in terms of safety issues, there are some general standards that apply to a variety of industries.
