A dynamic rope is a specially constructed, somewhat elastic rope used primarily in rock climbing, ice climbing, and mountaineering. This elasticity, or stretch, is the property that makes the rope dynamic —in contrast to a static rope that has only slight elongation under load.
Static ropes are designed to allow relatively little stretch, which is most useful for applications such as hauling and rappelling. Dynamic rope is used to belay climbers, and is designed to stretch under a heavy load to absorb the shock of a fallen climber. Dynamic ropes manufactured for climbing are tested by the UIAA. A test of "single ...
Dynamic rope, more commonly used in climbing, is used in caving for belaying cavers on climbs or using ladders. Static rope, once past its useful life for abseiling, is often used for fixed aids, such as handlines on climbs. The rope may be knotted to help climbers. Rope may also be recycled for digging.
If the climber falls, the belayer locks the rope and they will just hang from the rope at the point of the fall. [60] Top rope climbing is not free climbing or lead climbing, however, it is a popular way for beginners to start rock climbing, and to build up their strength and confidence to lead climb. [66] [67] Top rope solo climbing.
Some climbers will use a single full-thickness climbing rope of approximately 9–11 mm, and some will use double ropes, or "half-ropes", to reduce rope drag (e.g. one rope is clipped into any given anchor or protection point), which have a reduced thickness of approximately 8–9 mm to limit the weight of the extra rope.
Self-tests and over-the-counter remedies mean you don’t always need to see a doctor. Here's how to tell when you do.
This end of the rope is pulling the tug of war team to the right. Each segment of the rope is pulled by the two neighboring segments, stressing the segment in what is also called tension. Tension is the pulling or stretching force transmitted axially along an object such as a string, rope, chain, rod, truss member, or other object, so as to ...
Last year, there were 10.3 million cases of measles globally -- an increase of 20% from the previous year, according to a newly released report from the World Health Organization. Nearly 107,500 ...
