Can nylon ropes replaced by steel for mountain climbing?

Replacing nylon ropes with steel ropes for mountain climbing is not a viable or safe option. Here's why:

Weight: Steel is much heavier than nylon. A steel rope of the same length as a nylon rope would be significantly heavier, making it cumbersome and difficult to carry during a climb.

Rigidity: Steel ropes are much more rigid than nylon ropes. They do not have the same flexibility and elasticity as nylon, which is crucial for absorbing the impact of a fall and providing a dynamic response.

Abrasion Resistance: Steel is more susceptible to abrasion and damage from rocks and other sharp objects. Nylon ropes have better resistance to abrasion, which is important in a rugged mountain climbing environment.

Kinking and Tangling: Steel ropes are prone to kinking and tangling, especially if they are not properly managed. Kinks and tangles can create weak points in the rope and pose safety hazards.

Lack of Shock Absorption: Steel ropes have poor shock absorption capabilities compared to nylon ropes. This means that they do not stretch and absorb energy as well as nylon ropes, increasing the risk of injury in a fall.

Cost and Maintenance: Steel ropes are more expensive than nylon ropes. Additionally, they require more maintenance, including lubrication to prevent rust and corrosion.

Given these disadvantages, nylon ropes remain the preferred choice for mountain climbing due to their combination of strength, flexibility, and shock absorption properties.
