Study Notes
Wire Rope Characteristics
- A 6x12, two-inch wire rope indicates a configuration of six strands with twelve wires each, providing strength and flexibility.
- The diameter of the wire rope is two inches, which affects its load capacity and handling characteristics.
Safe Working Load
- A nylon line rated at 12,000 pounds breaking strain has a safety factor of five.
- This leads to a safe working load (SWL) of 2,400 pounds, calculated by dividing the breaking strain by the safety factor.
Metal Eye Splice
- A metal eye spliced into a wire forms a loop at the end of the rope, enhancing attachment options for various applications.
Stretch Properties of Ropes
- The line with the most stretch is nylon rope, known for its elasticity which can absorb shock loads effectively.
Advantages of Nylon Rope
- Nylon rope offers superior durability and resistance to abrasion compared to manila rope, making it more reliable in demanding conditions.
