Morphology
The phrase is compositionally built: 'friction' (resistance from rubbing) modifies 'yielding' (able to deform) which together describe the kind of 'prop' (support). A B1 learner who knows the constituent words can infer this refers to a support that yields because of friction, though finer technical details would require domain knowledge.
Etymology
Friction yielding prop names a support pole made so parts can slide and rub together: friction means rubbing, yielding means 'giving' a little, and prop is a support. Because the rubbing slows the slide, the prop can 'give' under pressure without breaking, so it takes ground movement safely.
