Question

Mountaineer generally use nylon rope for climbing mountains can nylon rope be replaced by cable made up of steel of equal strength?

Answer 1

No.

Nylon ropes are better suited for mountaineering because they have lower density than steel.

While climbing mountains, the thickness of the rope is also an important factor, as gripping a thicker rope is easier than gripping a thin one and for the same thickness nylon weighs much less than steel and also at that thickness steel will not be a cable but a rod
