a double knot
That would depend on the wall thickness everything being equal cast is heavier
What measure of units would you use to measure the thickness of a phone book
ring ropes are vinyl covered elevator cables. you would be hard pressed to find anything comparable.
Why would you want to add thickness?
This is an old sailing term. If you knew your ropes, you knew which rope on a sailing ship would do which task, and you were a good and experienced sailor. Nowadays, you say that any experienced person "knows the ropes."
Untie it as you would any other knot.

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.
This would be a line, which has no width, no thickness and no endpoints, but has infinite length.
thickness
22g thickness refers to a measurement in gauge of the thickness of material, such as metal. The lower the gauge number, the thicker the material. In this case, 22g thickness would indicate a relatively thin material.
No, why would they be? They all have equal success and they're a band together.
