Ball Screw - Driving Torque
A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical
Ripple factor (choke)
For the root mean square value of the ripple voltage, the calculation is more involved as the shape of the ripple waveform has a bearing on the result.

In science, buckling is a mathematical instability that leads to a failure mode.
When a structure is subjected to compressive stress, buckling may
The beam of a ship is its width at the widest point as measured at the ship’s nominal waterline. The beam is defined as a bearing projected at
Peukert’s law, presented by the German scientist Wilhelm Peukert in 1897, expresses the capacity of a battery in terms of the rate at which it is
