Screws

The theoretical mechanical advantage for a screw can be calculated using the following equation:United States Bureau of Naval Personnel, p. 5-4. :$MA = \frac$ where :''dm'' = the mean diameter of the screw thread :''l'' = the lead of the screw thread Note that the actual mechanical advantage of a screw ''system'' is greater, as a screwdriver or other screw driving system has a mechanical advantage as well. * Inclined plane: MA = length of slope ÷ height of the slope

* Balanced arm lamps * Gear ratio
