cuerda

Cuerda is the Spanish word for rope or cord—a flexible line used to bind, lift, tie, or transmit force. The term comes from Latin chorda, via Old Spanish cuerda. In everyday use it covers both natural fiber ropes (hemp, sisal, cotton, jute) and synthetic ropes (nylon, polyester, polypropylene).

Construction and varieties: Cuerda is commonly twisted (laid), braided, or plaited. Twisted ropes tend to be stiff but strong, braided ropes are smoother and more flexible, and synthetic fibers offer higher strength-to-weight ratios and resistance to moisture and rot. Natural fiber ropes are valued for traditional or marine applications and for low-stretch needs, while synthetic ropes dominate climbing, towing, forestry, and industrial rigging due to higher tensile strength and lower weight.

Applications: Ropes are used in sailing and fishing, construction and rigging, rescue operations, mountaineering and climbing, entertainment rigging, and general utility. In climbing, a distinction is often made between dynamic ropes, which absorb energy, and static ropes, which stretch minimally.

Care and safety: Rope performance depends on material, diameter, and condition. Inspect for fraying, cuts, core damage, chemical exposure, and UV degradation; avoid sharp edges and heat; retire worn or damaged rope according to manufacturer guidelines. Store dry and away from solvents.
