During the Renaissance the dynamics of the Mechanical Powers, as the simple machines were called, began to be studied from the standpoint of how much useful work they could perform, leading eventually to the new concept of mechanical work.

In 1586 Flemish engineer Simon Stevin derived the mechanical advantage of the inclined plane, and it was included with the other simple machines.

The length of the lever arm is particularly important ; choosing this length appropriately lies behind the operation of levers, pulleys, gears, and most other simple machines involving a mechanical advantage.

Submarine commanders were still expected to be able to calculate a firing solution by hand as a backup against mechanical failure, and because many submarines existing at the start of the war were not equipped with a TDC ; most could keep the " picture " in their heads and do much of the calculations ( simple trigonometry ) mentally, from extensive training.

The catastrophic vibrations that destroyed the bridge were not due to simple mechanical resonance, but to a more complicated interaction between the bridge and the winds passing through it — a phenomenon known as aeroelastic flutter.

Often used for fly fishing the fly reel or fly casting reel has traditionally been rather simple in terms of mechanical construction, little has changed from the design patented by Charles F. Orvis in 1874.

A very simple example of an instrumentation system is a mechanical

As a simple, cheap and reliable device, the Russian abacus was in use in all shops and markets throughout the former Soviet Union, and the usage of it was taught in most schools until the 1990s.

Intended for use in both training and daily activities like walking or performing chores, this simple measuring device may offer a solution for reducing obesity.

Gray also built a simple loudspeaker device into later models, which consisted of a diaphragm vibrating in a magnetic field.

Another recent theory ( see EPR paradox above ) resulting from the analysis of an EPR communication set up, has the simple device based on removing the effective retarded time terms in the Lorentz transform to yield a preferred absolute reference frame.

It was a simple device consisting of a cotton hood with two hoses which hung down to the floor, allowing the wearer to breathe the safer air found there.

The full-scale device built on this basis established the effectiveness of the mechanism's design, even with the simple materials and techniques available to the Byzantines.

This led Haldon and Byrne to theorize that the device was fundamentally different, " a simple syringe squirted both liquid fire ( presumably unignited ) and noxious juices to repel enemy troops.

This includes people who do simple modifications to graphing calculators, video game consoles, electronic musical keyboards or other device ( see CueCat for a notorious example ) to expose or add functionality to a device that was unintended for use by end users by the company who created it.

In a device that does not display text, a simple program to produce a signal, such as turning on an LED, is often substituted for " Hello world " as the introductory program.

The Liquid Crystal Display is intrinsically a “ passive ” device, it is a simple light valve.

The episode intertwined characters FBI agents Mulder and Scully, a simple apartment super, Henry Weems ( Willie Garson ) and an ailing young boy, Ritchie Lupone ( Shia LaBeouf ) in a real-life Goldberg device.

The nod to retroactive continuity is a joke meant to be shared between the writers and the viewers as a way of pointing out that anything done throughout the course of the series can easily be undone with a simple plot device ; it also points to parent show Doctor Whos frequent use of the device in its several-decade run.

A simple machine is an elementary device that has a specific movement ( often called a mechanism ), which can be combined with other devices and movements to form a machine.

simple: Data storage device

This device was installed in penny arcades, where people could watch short, simple films.

Initially, two major types of fission bombs were built: a relatively simple device that uses uranium-235 and a more complicated mechanism that uses plutonium-239 derived from uranium-238.

One popular program for converting Spectrum files from tape is Taper ; it allows connecting a cassette tape player to the line in port of a sound card, or — through a simple home-built device — to the parallel port of a PC.

A network hub, or repeater, is a simple network device.

In communications systems, a device that can sense an abnormal condition within the system and provide a signal indicating the presence or nature of the abnormality to either a local or remote alarm indicator, and ( b ) may detect events ranging from a simple contact opening or closure to a time-phased automatic shutdown and restart cycle.

Other systems may send hardware commands directly to peripheral devices or I / O controllers that cause an extremely simple input operation ( such as " read sector zero of the system device into memory starting at location 1000 ") to be carried out, effectively loading a small number of boot loader instructions into memory ; a completion signal from the I / O device may then be used to start execution of the instructions by the CPU.
