friction prop
- noun
- Specialized
- This design relies on the ability of the friction prop to yield under excessive load.
Examples
-
The miners installed a friction prop to provide temporary roof support in the tunnel.
-
Modern excavation sites often use adjustable friction props for added safety.
-
The engineer installed a new friction prop for stability.
-
Many friction props are used in mining operations.
-
Modern excavation sites often use adjustable friction props to support the structure safely.
-
The miners installed a friction prop to maintain the roof stability in the tunnel.
-
This friction prop is crucial for controlling yield under heavy loads in engineering projects.
Synonyms
A steel support used in mines or tunnels that lets parts slide to take pressure safely
A steel support post that slides to reduce pressure from the ground in mines or tunnels

Morphology
The compound is directly compositional: 'friction' (mechanical resistance) + 'prop' (a support) yields a support whose behavior is governed by friction. Although it is a technical engineering term, the noun-noun construction follows normal English composition patterns, so a B1 learner who knows both words can reasonably infer the meaning.
Etymology
Friction prop comes from a simple metal support made of two tubes that slide and are held by friction, and the word prop shows it is used to support things like a tunnel roof. Because the tubes can slip a little instead of breaking, the name tells us it is a support that can 'give' under heavy pressure.
