Force
... To find the sum of the two forces, graph the vectors and use the “head-totail” method. Follow these five steps: Step 1: Draw the 40-lb force. Draw a horizontal line on a sheet of notebook paper, or use a horizontal grid line on a sheet of graph paper. See Figure 1.12. Choose a convenient scale, such ...

... Figure 18.3 Free-body force diagrams for each body. The condition that the forces sum to zero is not sufficient to completely predict the motion of the beam. All we can deduce is that the center of mass of the system is at rest (or moving with a uniform velocity). In order for the beam not to rotate ...

... and the electrical properties of materials made with these components are decisively influenced by the behaviour of these dipoles in each others’ fields. Some materials are of course made up of neutral, non-polar components, but even these can have dipole moments induced by external fields. Consider ...
