this way the force applied at 210.] TOOTHED WHEELS. 221 the first is communicated to the second. There maybe a mechanical advantage with a corresponding loss ofspeed, or a gain in velocity and a consequent mechani-cal disadvantage. When the wheels are small, the teeth are nearly rect-angular in… … Fig. 153. may be a minimum. The detailed development of thissubject belongs to applied mechanics. As seen in Fig. 152, when the wheels are turned, theteeth roll upon one another so that the points in whichtheir mutual resistance is felt, due to the power andweight acting, lie very nearly at the…
