A hoisting device use chain, fibre or wire rope as its lifting medium. . Wire rope consists of several strands laid (or ‘twisted’) together like a helix.. Each strand is likewise made of metal wires laid together like a helix. . Rope According to National Fire Protection Association (NFPA) 1983, rescue rope falls into three classifications: life-safety rope, non-life-safety (utility) rope, and throwline (accessory cord).

Friction opposes motion. Friction is dependent on the texture of the surfaces. Friction is dependent on normal force. motion. friction. What do you Remember about Friction?. The use of one’s body to produce motion that is safe, energy conserving, and anatomically and physiologically efficient and that leads to the maintenance of a person's body balance and control. Benefits of Proper Body Mechanics.
