It is supposed that this simple longitudinal motion can be made to convey all kinds of information.
2.
The rarer "'Rall "'type combines rolling lift with longitudinal motion on trunnions when opening.
3.
It can also be used on resonators with other modes of vibration if the motion can be mechanically converted into a longitudinal motion.
4.
Most notably, the pitching moment being zero puts a constraint on the longitudinal motion of the aircraft that can be used to determine the elevator control input.
5.
Then the longitudinal motion is stopped and reversed, and the particle is reflected back towards regions of weaker field, the guiding center now retracing its previous motion along the field line, with the particle's transverse velocity decreasing and its longitudinal velocity increasing.

:: : : : : : Firing pin comes to mind, which seems to fit the rapid type of longitudinal motion better versus sinusoidal motion as associated with crank case rod or axial motion as associated with piston and rod ( pinion ) or with twisting motion as associated with drill rod .
