Mechanical movements also use a balance wheel together with the balance spring ( also known as a hairspring ) to control motion of the gear system of the watch in a manner analogous to the pendulum of a pendulum clock.

Mechanical toys use four types of different movements, rotary ( going around in a circle ), linear ( moving in a straight line then stopping ), reciprocating ( moving backwards and forwards continuously in a straight line ) and oscillating ( moving backwards and forwards in a curve ).

Mechanical movements get dirty and the lubricants dry up, so they must periodically be disassembled, cleaned, and lubricated.

The Mechanical forms – machine models including gears, pumps and regulators-are industrial tools used to demonstrate basic movements of modern machinery.

Mechanical calculators, like the base-ten addiator, the comptometer, the Monroe, the Curta and the Addo-X remained in use until the 1970s.

Mechanical separation methods use physical action to remove the trichomes from the plant, such as sieving through a screen by hand or in motorized tumblers.

Mechanical devices experienced a major expansion in their use in Ancient Greece and Ancient Rome with the systematic employment of new energy sources. especially waterwheels.

AutoLISP is a dialect of Lisp programming language built specifically for use with the full version of AutoCAD and its derivatives, which include AutoCAD Map 3D, AutoCAD Architecture and AutoCAD Mechanical.

Mechanical speed controllers use a network of resistors and switch between them by rotating a head with an electrode around a plate that has electrical contacts.

* Mechanical motion tracking systems like Gametrak use cables attached to gloves for tracking position of physical elements in three-dimensional space in real time.

Mechanical carriage of fragments of tumor cells by surgical instruments during operation or the use of needles during diagnostic procedures.

Mechanical flight is the use of a machine to fly.

Mechanical devices that allow amputees to walk again or continue to use two hands have probably been in use since ancient times, the most notable one being the simple peg leg.

The Method of Mechanical Theorems ( also referred to as The Method ) is a work by Archimedes which contains the first attested explicit use of indivisibles ( sometimes referred to as infinitesimals ).

Mechanical technology incorporated into the chair enabled adjustable chairs, especially for office use.

Louisiana State University Agricultural & Mechanical College had its origin in several land grants made by the United States government in 1806, 1811, and 1827 for use as a seminary of learning.

Mechanical dead space is defined as the volume of gas re-breathed as the result of use in a mechanical device.

** Mechanical air-conditioning, to cool the tank without the use of electric current which could reveal the position of the tank

Mechanical toys use several types of mechanisms.

The directors therefore asked its Chief Mechanical Engineer, Robert Billinton, to investigate the possible use of either steam or petrol railcars on the lightly used services.

Mechanical timers use mechanical clockwork to measure time.

Mechanical changes this year included the addition of GM's High Energy electronic ignition and a catalytic converter that mandated the use of unleaded gasoline.

Mechanical streak cameras use a rotating mirror or moving slit system to deflect the light beam.

Mechanical systems capture braking energy and use it to turn a small flywheel which can spin at up to 80, 000 rpm.

To maintain higher insulation values through the spline, manufacturers use Insulated Lumber, Composite Splines, Mechanical Locks, Overlapping OSB Panels, or other creative methods.

Mechanical calculation of the cycle is built into the Antikythera mechanism.

Mechanical snap action thermostat valves are the integration of the control mechanism with the flow control valve.

* Mechanical watch, utilizing a non-electric mechanism

This example has been removed by the manufacturer, The Tenghesvisie Mechanical Artillery Society, for further research into the winding mechanism and firing tests.

* Steering: Mechanical gyroscope powered by pressurized air ( GA VIII ) with anglesetting mechanism (+/- 90 degrees from initial course after launch )

Mechanical analog computers were very important in gun fire control in World War II, The Korean War and well past the Vietnam War ; they were made in significant numbers.

Mechanical cultivation and hand weeding were often necessary to control weeds not controlled by herbicide applications.

At many universities, control engineering courses are taught in Electrical and Electronic Engineering, Mechatronics Engineering, Mechanical engineering, and Aerospace engineering ; in others it is connected to computer science, as most control techniques today are implemented through computers, often as embedded systems ( as in the automotive field ).

Mechanical changes can make equipment ( and control systems ) more stable.

Mechanical and hydro-mechanical flight control systems are relatively heavy and require careful routing of flight control cables through the aircraft by systems of pulleys, cranks, tension cables and hydraulic pipes.

Mechanical control ( including tillage ) was also ( and still is ) used to control weeds.

" Mechanical " or " forced " ventilation is provided by an air handler and used to control indoor air quality.

Mechanical methods of control involve cutting off crowns from roots, usually just below ground level.
