Morphology
mechanical + yielding + prop
The compound literally combines 'mechanical' + 'yielding' + 'prop', so a B1 learner who knows those words can infer it is a support that yields or deforms in a mechanical way to provide stability. However, the precise technical meaning (controlled yielding achieved via frictional sliding surfaces or telescopic tubes) is specialized and not predictable from the constituents alone, making it only partially transparent.
Etymology
Mechanical yielding prop comes from its literal design: a metal prop whose yielding parts are inner tubes that slide so it can 'give a little' when heavy weight presses on it. That's why the name means a support that moves in a controlled way to 'absorb pressure' and protect tunnels or structures.
