Check all five boxes on the right hand side (applied force, spring force, displacement, equilibrium, values). Key Points on Hooke's Law: 1) Hooke's Law: As the force increases so does the deformation,proportionally. Note how it models the combination of motion, damping, and mechanical deformation. Figure out the red one using both Hooke's Law and S. The deformation and force on the knitted fabric is modelled using Hooke's Law, which results in a more realistic and faster simulation. For example, if the member is experiencing a load in the y-direction (which in turn causes a stress in the y-direction), the Hooke's Law shows that strain in the x-direction does not equal to zero. It would be incorrect to imply that the development in all of these fields had reached the same level. Spring-mass system. The area compressibility modulus obtained from the analysis of the CU area fluctuations is fully consistent with the Hooke's law route.
