par un jeu de différences de ces points by measuring the deformation at these points Explanation: jeu means also "amplitude of movement" as in "jeu de vis" how much the screw is loose/moving in relation to the nut, here "jeu" is the movement of metal parts under effort/tension (deformation), which is an indication of the force applied to it as long as it's in the range of elastic deformation. Measuring this "jeu" is way of measuring "les tensions" - same principle as a spring balance weighing scales, only the deformations are much smaller. -------------------------------------------------- Note added at 2 hrs (2013-05-03 12:15:04 GMT) -------------------------------------------------- the "deformation" of the metal is "the difference in position" / "the relative displacement" of this measuring points. -------------------------------------------------- Note added at 3 hrs (2013-05-03 12:25:26 GMT) -------------------------------------------------- Par un jeu de différences de ces points, il est possible d’obtenir trois tensions VX, VY et VZ qui sont liées, by measuring the deformation at these points, it is possible to deduct the values of the 3 related forces VX, VY et VZ "... Stress and Strain Stress The term stress (s) is used to express the loading in terms of force applied to a certain cross-sectional area of an object. From the perspective of loading, stress is the applied force or system of forces that tends to deform a body. From the perspective of what is happening within a material, stress is the internal distribution of forces within a body that balance and react to the loads applied to it. The stress distribution may or may not be uniform, depending on the nature of the loading condition. For example, a bar loaded in pure tension will essentially have a uniform tensile stress distribution. However, a bar loaded in bending will have a stress distribution that changes with distance perpendicular to the normal axis. ..." [http://www.ndt-ed.org/EducationResources/CommunityCollege/Ma...] |
