Most focus on providing general improvements such as a higher mechanical efficiency, speed, or load capacity.

For mechanical efficiency, opposite arms usually swing with each leg while marching.

Live, the music has a mechanical efficiency and few surprises.

Low idle speed due to increase in mechanical efficiency at the top of the stroke.

For a given pressure, the highest mechanical efficiency is usually found in the middle third of the volume column.

From this, a greater mechanical efficiency and working life are claimed.

All this was done with a mechanical efficiency that bespoke routine.

The amount of moving parts in a machine is a factor in its mechanical efficiency.

An electrical transformer, for example, has no moving parts, and its mechanical efficiency is generally above the 90% mark.

All these have brought mechanical efficiency to their subjects at the cost of more intangible values.
