Name the material used for making ropes for rock climbing?
First off, there are static and dynamic ropes. Static ropes do not stretch and are mostly used for rappelling, hauling, fixed lines, and probably some other stuff I do not know about. This is because none of these activities involve large forces - such as what would be created during a fall. Dynamic ropes stretch, and are the main type of rope used for rock climbing. This is because they stretch to absorb the shock of the climbing rope. In fact, if I remember correctly, some rock climbing ropes can stretch to as much as 30% more than it's original length. Dynamic ropes come in a wide range of diameters and can also be divided into three categories - single ropes, half ropes, and twin ropes. One would choose a certain diameter and type of rope based on the activity they plan on doing.
What type of Rope has the least amount of stretch?
Dyneema (HMPE) ropes have the least amount of stretch compared to other rope types due to their low elongation properties. These ropes are lightweight, strong, and have minimal stretch, making them ideal for applications where low stretch is crucial, such as in sailing and rigging.
Can nylon ropes replaced by steel for mountain climbing?
No. Climbing ropes are built to stretch. If you took a 15-20ft fall on a rope without any stretch (like with a steel cable) it would catch you just fine, but it would also snap your spine. Newton's second law: Force equals mass times acceleration. If there is no stretch your (de)acceleration is very high, this results in forces that are very high. My organs and bones don't like very high forces.
What common phrase originated when 'bedsprings' were ropes woven through wooden bed frames and needed to be kept from sagging by using a key to stretch them?
The common phrase that originated from this practice is "sleep tight." It refers to tightening the ropes on the bed frame to ensure a taut sleeping surface.
Why are the main support cables of the suspension cables designed to sag?
They can't be designed not to. Large cables and ropes are extremely different to stretch straight, because of their high weight-to-length ratio.

Cellular ropes made of repeating units of the protein actin?
These cellular ropes are called actin filaments. Actin is a globular protein that polymerizes to form these filaments, which are essential for various cellular processes such as cell movement, division, and shape maintenance. The highly dynamic nature of actin filaments allows cells to quickly reorganize their internal structure in response to external signals.
