Which type of rope is best suited for resisting dynamic load?

Nylon is the best choice for resisting dynamic loads due to its superior elasticity and strength characteristics. When subjected to sudden forces, such as in a fall or a shock load, nylon can absorb more energy without breaking compared to other materials. This elasticity allows it to stretch under load, which helps to reduce the impact force that is transmitted through the rope, thereby minimizing the risk of failure.

In contrast, polyester, while strong and resistant to UV damage and abrasion, does not possess the same level of elasticity as nylon, making it less effective in dynamic situations. Hemp and manila ropes are natural fibers that are not designed to withstand heavy dynamic loads; they are less elastic and more prone to breaking under sudden stress. Thus, nylon's combination of strength, elasticity, and energy absorption capabilities makes it the most suitable choice for scenarios involving dynamic loads.
