👉 Rivetless is a term in the context of engineering, particularly in mechanical systems and processes. It refers to an object that can be tightened or loosened without breaking or altering its dimensions. In mechanics, a "rivetless" system is one where there are no external forces acting on the system during operation. This means that the system does not require any external force to maintain its state of rest or motion. For example, in a mechanical pulley system, both the pulleys and the
