However if the attic is intended for storage the attic live load or some portion should also be considered for the design of other elements in the load path.
Different design methods are used but they typically defined the load cases or combination stress or strength limits and deflection limits.
Several of the tooling and casting requirements of a part can be addressed at the design stage.
