Define proof load
WebThe ultimate load is the design limit load multiplied by a factor of safety and is usually the most critical load in the design procedure. The proof load is the limit load multiplied by the proof load factor and is used to test parts of the structure before the entire spacecraft or launch vehicle is tested. Such a test, for example, would be ... WebThe proof load represents the usable strength range for certain standard fasteners. By definition, the proof load is an applied tensile load that the fastener must support …
