ABSTRACT
Very often bending and torsion do not act alone when designing a component; they can often act simultaneously. As an example, a shaft that is supported as a cantilever with a drive pulley fitted on the free end will in this case be resisting a bending load due to the drive belt or chain tension and a torsion load again imposed due to the drive belt or chain. This example is not restricted to rotating shafts but can equally be applied to brackets or other nonrotating components.
