Final answer:
A fall arrest system is any mechanism used to dissipate a substantial amount of energy during a fall arrest or limit the energy imposed on an employee during a fall arrest. Specially woven lanyards are one example of fall arrest systems that dissipate energy by stretching and absorbing kinetic energy. This concept is important in physics to understand how to protect against fall-related injuries.
Step-by-step explanation:
A fall arrest system is any mechanism used to dissipate a substantial amount of energy during a fall arrest or limit the energy imposed on an employee during a fall arrest. These mechanisms can include rope grabs, rip stitch lanyards, specially woven lanyards, tearing or deforming lanyards, and more.
One example of a fall arrest system that dissipates energy is a specially woven lanyard. When a person falls, the lanyard is designed to stretch and absorb some of the kinetic energy of the fall. This stretching and deformation of the lanyard helps limit the force experienced by the person.
In physics, the concept of energy dissipation is important in understanding how to protect against fall-related injuries. Fall arrest systems are designed to minimize the impact forces exerted on a person during a fall and prevent potential injuries.
