Force and torque measurement

In this article, we will focus on determining the “mechanical actions” exerted on an object in motion or at rest in a given reference frame. These mechanical actions result from interactions between the object and its environment (via solid-solid contacts, gravitational interactions, electromagnetic interactions, etc.). In accordance with the laws of dynamics (see below), we define a force F as a mechanical action exerted on a material point M, for which the following...
