The organization is known for setting codes and standards for mechanical devices. ...more on Wikipedia about "American Society of Mechanical Engineers"
ASTM International is an international voluntary standards organization that develops and produces technical standards for materials, products, systems and services. It was formed in 1898 in the United States as the American Society for Testing and Materials by a group of scientists and engineers, led by Charles Benjamin Dudley, who wanted to address the frequent rail breaks plaguing the fast-growing railroad industry. The group developed a standard for the steel used to fabricate rails. ...more on Wikipedia about "ASTM International"
A ball detent is a simple mechanical arrangement used to hold a moving part in a temporarily fixed position relative to another part. Usually the moving parts slide with respect to each other, or one part rotates within the other. ...more on Wikipedia about "Ball detent"
A bell crank is a type of crank that changes motion around a 90 degree angle. The name comes from its first use, changing the vertical pull on a rope to a horizontal pull on the striker of a bell, used for calling servants in upper class British households. ...more on Wikipedia about "Bell crank"
A cam is a projecting part of a rotating wheel or shaft that strikes a lever at one or more points on its circular path. The cam can be a simple tooth, as is used to deliver pulses of power to a steam hammer, for example, or an eccentric disc or other shape that produces a smooth oscillating motion in the lever. ...more on Wikipedia about "Cam"
A cantilever is a beam carrying loads to a strong mounting point with one end of the beam anchored, and having the other end suspended in the air. The beam forms a lever, which carries the load by being held in position by the mount, turning the loads into torque on the mount. Cantilever construction allows for long structures without external bracing. ...more on Wikipedia about "Cantilever"

A centrifugal governor is a specific type of governor that controls the speed of an engine by regulating the amount of fuel admitted, so as to maintain a near constant speed whatever the load or fuel supply conditions. It uses the principle of proportional control. ...more on Wikipedia about "Centrifugal governor"
In mechanical engineering, a clockwork is either a lightweight mechanical linkage, especially one involving multiple axles, or a complete mechanical device whose functioning relies on internal clockwork (in the preceding sense), especially where muscular effort is the sole source of operating power. ...more on Wikipedia about "Clockwork"
Collapse action is a device behaviour that snaps a switch into place, usually using a bistable element. When flipping a light switch, strain on one spring increases until it flips position, pulling down the switch. Collapse action allows you to remove your hand from the switch without risk it falls to the down position, as the force needed to overcome the resistance is too great. The action also does not exert force in the lower position, avoiding the spontaneous rise to the up position that a spring invites. ...more on Wikipedia about "Collapse action"
A crank is a bent portion of an axle, or shaft, or an arm keyed at right angles to the end of a shaft, by which motion is imparted to or received from it; also used to change circular into reciprocating motion, or reciprocating into circular motion. Familiar examples of a crank for manual use include the crank on a manual pencil sharpener and the cranks on the pedals that drive a bicycle. ...more on Wikipedia about "Crank (mechanism)"
In mechanical engineering, a dog is a protrusion on a shaft or other component for the purposes of correct orientation and for transmitting torque. For example, a dog clutch is a means to couple two rotating shafts and is widely used in automotive transmissions. ...more on Wikipedia about "Dog (mechanics)"

Dropping Point is a qualitative property of lubricating grease that gives a general indication of the temperature at which a grease passes from a semi-solid to liquid state under specific test conditions. It is a measure of the heat resistance of a grease. ...more on Wikipedia about "Dropping point" The view on www.shortopedia.com.
An engine is something that produces some effect from a given input. The origin of engineering was the working of engines. There is an overlap in English between two meanings of the word "engineer": 'those who operate engines' and 'those who design and construct new items'. ...more on Wikipedia about "Engine"
Engineering mechanics, also called Theoretical and Applied Mechanics, is a branch of the physical sciences which looks to understand the actions and reactions of bodies at rest or in motion. Much of modern engineering mechanics is based on Isaac Newton's laws of motion while the modern practice of their application can be traced back to Timoshenko, who is said to be the father of modern engineering mechanics. ...more on Wikipedia about "Engineering mechanics"
The elementary Euler-Bernoulli beam theory is a simplfication of the linear isotropic theory of elasticity which allows quick calculation of the load-carrying capacity and deflection of common structural elements called beams. It was first enunciated circa 1750, but was not applied on a large scale until the development of the Eiffel Tower and the Ferris Wheel in the late 19th century. Following these successful demonstrations, it quickly became a cornerstone of engineering and an enabler of the Second Industrial Revolution. ...more on Wikipedia about "Euler-Bernoulli beam equation"
A Feedwater heater is a power plant component used to pre-heat water delivered to the boiler. Preheating the feedwater reduces the amount of energy needed to make steam and thus reduces plant operation costs. This improves the thermodynamic efficiency of the system, and also helps to avoid thermal shock to the boiler metal when the feedwater is introduced back into the steam cycle. ...more on Wikipedia about "Feedwater heater"
Fluid dynamics is the subdiscipline of fluid mechanics that studies fluids ( liquids and gases) in motion. The discipline has a number of subdisciplines, including aerodynamics (the study of gases) and hydrodynamics (the study of liquids). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns. Some of its principles are even used in traffic engineering, where traffic is treated as a continuous fluid. ...more on Wikipedia about "Fluid dynamics"
A four bar linkage or simply a 4-bar or four-bar is the simplest movable linkage. It consists of 4 rigid bodies (called bars or links), each attached to two others by single joints or pivots to form a closed loop. ...more on Wikipedia about "Four bar linkage"
A gear coupling is a mechanical device for transmitting torque between two shafts that are not coaxial. It consists of a flexible joint fixed to each shaft. The two joints are connected by a third shaft, called the spindle. ...more on Wikipedia about "Gear coupling"

The Geneva drive is a mechanism that translates a continuous rotation into an intermittent rotary motion. It is an intermittent gear where the drive wheel has a pin that reaches into a slot of the driven wheel and thereby advances it by one step. The drive wheel also has a raised circular blocking disc that locks the driven wheel in position between steps. ...more on Wikipedia about "Geneva drive"
A gimbal is a device using Euler angles to measure the rotation of an object in three dimensions and to control that rotation. The device is usually a set of two or three rings, mounted on axes at right angles, so as to allow a compass or a ball to remain suspended in a horizontal plane, regardless of the motion of its support. ...more on Wikipedia about "Gimbal"
A heat exchanger is a device built for efficient heat transfer from one fluid to another, whether the fluids are separated by a solid wall so that they never mix, or the fluids are directly contacted. They are widely used in refrigeration, air conditioning, space heating, power production, and chemical processing. One common example of a heat exchanger is the radiator in a car, in which the hot radiator fluid is cooled by the flow of air over the radiator surface. ...more on Wikipedia about "Heat exchanger" The text you are reading is from shortopedia
