Between the pushing and pulling of the atomic forces, it is as if each atom is connected to its neighboring atom by a spring. The spring is made up of millions of smaller atomic springs, in the same way that an apple is pulled toward the Earth by the force of the gravity spring. Of course, these aren t tiny physical springs inside our big spring. They are the forces that keep our universe together. Strain occurs when you pull or push the atoms in an object against the atomic forces that are working to keep them in place. The object then changes shape, or deforms. This deformation is the visible manifestation of the strain inside an object. You feel the strain by the force of the object trying to return to its original shape. Of course, if you put too much strain into something, the atoms can be pushed and pulled too far and break their internal springs. Then the object bends or breaks, and its stored potential energy is rearranged so we can t use it anymore. When you stretch or compress a spring, it pushes back with the force of: F k l 2-7 edit pdf text online free without watermark: 7 Best Free PDF Editors (Updated June 2019) - Lifewire pdf text editing software free online Smallpdf.com - A Free Solution to all your PDF Problems

Fig 510: Precitech 4 inch vacuum chuck [4] (7-49a) k is the spring constant, which describes how springy the spring is, and l is how far the spring has been stretched or squished (Fig. 2-13). The spring s force pushes in the opposite direction of the force used to deform it. The spring s stored force exactly matches the force it took to deform it. The same with a rubber band, though rubber bands are only useful in the stretch direction. In robotics, you can use the force stored in a spring or rubber band to push against the acceleration of gravity, to make it easier for the robot s motors to lift something. Springs can also be used to hold something in position, to keep it from moving.
