(OP)
In the NEC, Article 210.4, what is meant by a "yoke"? I can't seem to find a good definition anywhere.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: What is meant by a "yoke"?
Most commonly, this references two parts of a duplex receptacle where a break-off tab is used to serve them from two different hot wires (a "split-wire" receptacle). In this case, they must be served by a two-pole breaker or single-pole breakers with an approved handle tie so that both hot wires are disconnected at the same time.

Yoke (rotating machinery) (magnetic) is the element of ferromagnetic material, not surrounded by windings, used to connect the cores of an electromagnet, or of a transformer, or the poles of a machine, or used to support the teeth of the stator or rotor.
This appears to be the closest definition to what is meant in the code. Simply: yoke=support=tie=etc.

Legs = wound limbs = the section of core upon which the coils are mounted
Yoke = the sections of core joining the wound limbs
Normally' Legs can be considered to be the vertical parts and yokes the horizontally parts connecting the legs
