DAll of the above
Answer:
D. All of the above
Read Explanation:
When performing rope work to secure objects firmly together, the choice of lashing depends on how the objects are positioned relative to each other.
Square Lashing
Square lashing is used to join two poles that are positioned at a right angle (90°) to each other. It's particularly effective for creating load-bearing joints in structures like ladders, frames, or towers, as it prevents the poles from sliding against each other. The technique involves a series of wraps and "frapping" turns, which are wraps that go around the lashing itself, pulling it tight to cinch the poles together. 🛠️
Diagonal Lashing
Diagonal lashing is used when two poles or spars cross each other but do not touch. It is designed to pull the poles tightly together and prevent "racking," which is the scissoring or shifting motion of a structure. This type of lashing is often used for creating cross-braces on structures like trestles, providing stability and strength.
Figure-of-Eight Lashing
Figure-of-eight lashing, also known as tripod lashing, is specifically used to bind three poles together at one end to form a tripod. The rope is woven in a figure-of-eight pattern between the poles, and then frapped to tighten the lashing. This creates a versatile, free-standing structure that can be used for a variety of purposes, such as a camp washstand or a support for a cooking pot over a fire. 🏕️
