n of the dotted arrow; let Vbe theforce with which the block is pushed against the table and let Hbe the force necessary to keep the block in motion. Then sincethe ratio H/V is constant (that is, if V is large, H is large inproportion), it is evident that the angle <p between V and the… … 120 ELEMENTS OF MECHANICS. Figure 486 represents the table TT tipped so as to bring theforce F into a vertical position. In this case the force F may bethought of as the pull of gravity on the block B, and the com-ponent of F parallel to the table (namely H) is barely sufficientto cause the block…
