Hyperdynamic precordium is a condition where the precordium (the area of the chest over the heart) moves too much (is hyper dynamic) due to some pathology of the heart. That means a forceful and hyperdynamic impulse ( large amplitude that terminates quickly) can be palpated during physical examination. [ 1 ]
In anatomy, the precordium or praecordium is the portion of the body over the heart and lower chest. [1] Defined anatomically, it is the area of the anterior chest wall over the heart. It is therefore usually on the left side, except in conditions like dextrocardia, where the individual's heart is on the right side. In such a case, the ...
Structural dynamics is a type of structural analysis which covers the behavior of a structure subjected to dynamic (actions having high acceleration) loading. Dynamic loads include people, wind, waves, traffic, earthquakes, and blasts. Any structure can be subjected to dynamic loading.
Steel frame structure Rectangular steel frame, or "perimeter frame" of the Willis building (at right) contrasted against the diagrid frame at 30 St Mary Axe (at center), in London. Steel frame is a building technique with a " skeleton frame" of vertical steel columns and horizontal I-beams , constructed in a rectangular grid to support the ...
In the physical science of dynamics, rigid-body dynamics studies the movement of systems of interconnected bodies under the action of external forces.The assumption that the bodies are rigid (i.e. they do not deform under the action of applied forces) simplifies analysis, by reducing the parameters that describe the configuration of the system to the translation and rotation of reference ...
The design and use of steel frames are commonly employed in the design of steel structures. More advanced structures include steel plates and shells . In structural engineering, a structure is a body or combination of pieces of the rigid bodies in space that form a fitness system for supporting loads and resisting moments .
A non-inertial reference frame (also known as an accelerated reference frame [1]) is a frame of reference that undergoes acceleration with respect to an inertial frame. [2] An accelerometer at rest in a non-inertial frame will, in general, detect a non-zero acceleration. While the laws of motion are the same in all inertial frames, in non ...
Locomotive frame of a LNER Gresley Pacific locomotive during construction. A locomotive frame is the structure that forms the backbone of the railway locomotive, giving it strength and supporting the superstructure elements such as a cab, boiler or bodywork. The vast majority of locomotives have had a frame structure of some kind.
