In physics and engineering, a free body diagram ( FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a body in a given condition. It depicts a body or connected bodies with all the applied forces and moments, and reactions, which act on the body (ies).
Chainset: see Crankset. Chainstay: a pair of tubes on a bicycle frame that runs from the bottom bracket to the rear fork ends. Chain tensioner: a device to maintain proper chain tension. Chaintug: a device to aid in setting the proper chain tension. Cluster: a bicycle cogset, either a freewheel, or cassette.
Aircraft flight dynamics. Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch, roll and yaw. These are collectively known as aircraft attitude, often ...
Body-on-frame is a traditional motor vehicle construction method whereby a separate body or coach is mounted on a strong and relatively rigid vehicle frame or chassis that carries the powertrain (the engine and drivetrain) and to which the wheels and their suspension, brakes, and steering are mounted. Whereas this was the original method of ...
A micrometer, sometimes known as a micrometer screw gauge, is a device incorporating a calibrated screw widely used for accurate measurement of components [1] in mechanical engineering and machining as well as most mechanical trades, along with other metrological instruments such as dial, vernier, and digital calipers.
For example, a free body diagram of a block sitting upon an inclined plane can illustrate the combination of gravitational force, "normal" force, friction, and string tension. [note 4] Newton's second law is sometimes presented as a definition of force, i.e., a force is that which exists when an inertial observer sees a body accelerating.
Constitutional psychology is a theory developed by Sheldon in the 1940s, which attempted to associate his somatotype classifications with human temperament types. [4] [5] The foundation of these ideas originated with Francis Galton and eugenics. [2] Sheldon and Earnest Hooton were seen as leaders of a school of thought, popular in anthropology ...
Between them, the work on display ranges from Muholi’s best-known photographs to their new bronze sculptures. Yet Muholi doesn’t refer to themself as an artist; instead they prefer the term ...
