A test of "single" standard rope involves tying an 80 kg (176 pound) weight to the end of a length of rope. This weight is then dropped 5 meters (16½ feet) on 2.7 meters (9 feet) of rope, with the rope running over a rounded surface simulating that of a standard carabiner. This process is repeated until the rope breaks.
The mechanical advantage is 2, requiring a force of only 50 N to lift the load. A block and tackle is characterized by the use of a single continuous rope to transmit a tension force around one or more pulleys to lift or move a load. Its mechanical advantage is the number of parts of the rope that act on the load. The mechanical advantage of a ...
Example of a high ropes course at night Rope climbing at the Alpine Center Bottrop, built by insight-out, Germany. A ropes course is a challenging outdoor personal development and team building activity which usually consists of high elements, low elements, or some combination of the two.

In stricter senses, the term wire rope refers to a diameter larger than 9.5 mm (3 ⁄ 8 in), with smaller gauges designated cable or cords. [1] Initially wrought iron wires were used, but today steel is the main material used for wire ropes. Historically, wire rope evolved from wrought iron chains, which had a record of mechanical failure.
