What is the term for the increase in load on a rope due to sudden stops, swings, starts, or vibrations?

The term that describes the increase in load on a rope caused by sudden stops, swings, starts, or vibrations is known as a dynamic load. Dynamic loads are characterized by changes in magnitude and direction, often occurring in real-time as the load is applied or removed. This type of loading is critical to consider in various applications, including those in HVAC systems where moving parts can create sudden forces that affect tension in ropes or cables.

Unlike static loads, which remain constant over time and do not change unless the system is altered, dynamic loads are variable and can lead to impacts in the system that must be managed for safe and effective operation. A thorough understanding of dynamic loads is essential for designing systems that are both robust and capable of handling the forces encountered during operation.
