Uso de cuplas o pares de fuerzas para expresar el torque en situaciones de equilibrio estático [PDF]

open access: yesRevista Brasileira de Ensino de Física, 2021
Un cuerpo rígido está en equilibrio estático si se cumplen las siguientes dos condiciones: la suma de fuerzas externas es cero, y la suma de los momentos de torsión (o torques) externos es cero. La condición de equilibrio de torques presenta dificultades

On the Internal Counter-Torque between Springs in Serially Connected Statically Balanced Manipulators

open access: yesMachines, 2023
Serially connected statically balanced manipulators with springs have been used in many applications. However, a portion of the torques caused by springs countering each other lead to an imbalance in gravitational torques and, therefore, are deemed as ...

Inertial torques acting on a spinning paraboloid

open access: yesAIP Advances, 2020
Numerous gyroscopic devices consist of rotating components that manifest gyroscopic effects, i.e., the action of unexplainable inertial torques. The rotating objects in engineering can be designed as a disk, cylinder, rotor, circular cone, sphere ...

Individuals With Hemiparetic Stroke Accurately Match Torques They Generate About Each Elbow Joint

open access: yesFrontiers in Neuroscience, 2019
Background: Successful execution of a task as simple as drinking from a cup and as complicated as cutting food with a fork and knife requires accurate perception of the torques that one generates in each arm.

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

open access: yesFEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.
