braided
The ------ -------- of rope is the tensile strength divided by the working load limit correct answer design
factor
Carabiners must always be loaded along their ______ ________ and never across the gate correct
answer major axis
------ --------- are heavy duty pulleys with a large rotating sheave for the lowering line, and smmaler, fixed
sheave to accept a rope sling. In contrast, ----- ------ are designed for static, overhead rigging, where the
loads are known and very low friction is required correct answer arborist blocks, rescue pulleys
