The process' other disadvantages are mechanical complexity and large number of moving parts.

The limitations on this system appear to be mainly in the mechanical complexity, bulk and mass of the equipment.

Two and three-spool designs are common, beyond that the mechanical complexity is too great.

This led to considerable mechanical complexity, which only grew over time as additional correction factors were added to the design.

The added mechanical complexity was found to be of dubious value, as reflected in their limited production and use.

However, the mechanical complexity required precision assembly and high quality materials.

It required greater mechanical complexity of the player.

In addition to lower mechanical complexity, the interdependent servos share the workload.

The efficiency of a contra-rotating prop is somewhat offset by its mechanical complexity.

The name is possibly referencing the mechanical complexity of calliopes.
