The concept is essential, for instance, for understanding the net effect of multiple forces applied to a body. For example, if two forces of equal magnitude act upon a rigid body along the same line of action but in opposite directions, they cancel and have no net effect. But if, instead, their lines of action are not identical, but merely ...
Magnetic force is used to counteract the effects of the gravitational force and any other forces. [ 2 ] The two primary issues involved in magnetic levitation are lifting forces : providing an upward force sufficient to counteract gravity, and stability : ensuring that the system does not spontaneously slide or flip into a configuration where ...
A rubber sheet, for example, behaves more like glass at typical bullet speeds. That is, it fractures, and does not stretch or vibrate. The field of applications of impact theory ranges from the optimization of material processing, impact testing, dynamics of granular media to medical applications related to the biomechanics of the human body ...
Eberhard effect (science of photography) Edge effect (ecological succession) (ecology) Edison effect (atomic physics) (electricity) (Thomas Edison) (vacuum tubes) Efimov effect (physics) Einstein effect (disambiguation), several different effects in physics; Einstein–de Haas effect (science) Electro-optic effect (nonlinear optics)
A structural load or structural action is a mechanical load (more generally a force) applied to structural elements. [1] [2] A load causes stress, deformation, displacement or acceleration in a structure. Structural analysis, a discipline in engineering, analyzes the effects of loads on
The normal force, for example, is responsible for the structural integrity of tables and floors as well as being the force that responds whenever an external force pushes on a solid object. An example of the normal force in action is the impact force on an object crashing into an immobile surface. [4]: ch.12 [5]
Scientists are concerned about the effect of such a system on the inner ear of the occupants. The concern is that using centripetal force to create artificial gravity will cause disturbances in the inner ear leading to nausea and disorientation. The adverse effects may prove intolerable for the occupants. [5]
The Magnus effect is named after Heinrich Gustav Magnus, the German physicist who investigated it. The force on a rotating cylinder is an example of Kutta–Joukowski lift, [2] named after Martin Kutta and Nikolay Zhukovsky (or Joukowski), mathematicians who contributed to the knowledge of how lift is generated in a fluid flow.
