  2. Strain (injury) - Wikipedia

    en.wikipedia.org/wiki/Strain_(injury)

    A strain can occur as a result of improper body mechanics with any activity (e.g., contact sports, lifting heavy objects) that can induce mechanical trauma or injury. Generally, the muscle or tendon overstretches and is placed under more physical stress than it can withstand. [1]

  3. Sports biomechanics - Wikipedia

    en.wikipedia.org/wiki/Sports_biomechanics

    Sports biomechanics is the quantitative based study and analysis of athletes and sports activities in general. It can simply be described as the physics of sports. Within this specialized field of biomechanics, the laws of mechanics are applied in order to gain a greater understanding of athletic performance through mathematical modeling, computer simulation and measurement.

  4. Ergonomic hazard - Wikipedia

    en.wikipedia.org/wiki/Ergonomic_hazard

    Environmental, operational, or design factors can all negatively impact a worker or user; examples include whole-body or hand/arm vibration, poor lighting, or poorly designed tools, equipment, or workstations. Some of the common body regions where injuries may occur include: Muscles or ligaments of the lower back; Muscles or ligaments of the neck

  5. Multibody system - Wikipedia

    en.wikipedia.org/wiki/Multibody_system

    The following example shows a typical multibody system. It is usually denoted as slider-crank mechanism. The mechanism is used to transform rotational motion into translational motion by means of a rotating driving beam, a connection rod and a sliding body. In the present example, a flexible body is used for the connection rod.

  6. Anelasticity - Wikipedia

    en.wikipedia.org/wiki/Anelasticity

    Anelasticity is therefore by the existence of a part of time dependent reaction, in addition to the elastic one in the material considered. It is also usually a very small fraction of the total response and so, in this sense, the usual meaning of "anelasticity" as "without elasticity" is improper in a physical sense.

  7. Analytical Dynamics of Particles and Rigid Bodies - Wikipedia

    en.wikipedia.org/wiki/Analytical_Dynamics_of...

    In a 2015 article on modern dynamics, Miguel Ángel Fernández Sanjuán wrote: "When we think about textbooks used for the teaching of mechanics in the last century, we may think on the book A Treatise on the Analytical Dynamics of Particles and Rigid Bodies" as well as Principles of Mechanics by John L. Synge and Byron A. Griffith, and ...

  8. Many-body problem - Wikipedia

    en.wikipedia.org/wiki/Many-body_problem

    Microscopic here implies that quantum mechanics has to be used to provide an accurate description of the system. Many can be anywhere from three to infinity (in the case of a practically infinite, homogeneous or periodic system, such as a crystal), although three- and four-body systems can be treated by specific means (respectively the Faddeev and Faddeev–Yakubovsky equations) and are thus ...

  9. Impact (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Impact_(mechanics)

    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 ...
