... a free-body diagram shows all of the external forces (that is, forces due to other objects) acting on a given object. There are undoubtedly also internal forces acting within the object; each atom might be pushing or pulling on the atom next to it. But these internal forces cancel in pairs (by Newto ...

... keep the box from moving. The free-body diagram of this situation is shown in Figure 5.3c. 10 N is below the 20 N maximum value, so the box will not move. Step 3 - What is the force of friction acting on the box if you increase your force to 15 N? This situation is similar to step 2. Now, the force ...

The Lagrangian Method
... above theorem shows that if (and only if, as you can show by working backwards) we have a stationary value of S, then the E-L equations hold. And the E-L equations are equivalent to F = ma (as we showed for Cartesian coordinates in Section 6.1, and as we’ll prove for any coordinate system in Section ...

... Objects respond to compressive and tensile forces by deforming. This is evident in objects such as springs and rubber bands when under load. How much an object deforms depends on the magnitude of the applied force and the physical properties of the material it is made from. The bones, muscles and te ...
