^ to figure the fivedimensions indicated in Fig. 25, three of which, A, B, and C, are angles, and two, E and F, arenecessary to determine the outside diameter and backing. Only one of these, A, is useddirectly. B is called the angle increment, C the angle decrement, E is one-half the… … t a b = m t r tan B a b = D --f 2 sin A 2 sin A d P d t m cos A F = - sin A 2 sin A The angle decrement, C, is sometimes made equal to B, in which case thededendum of the tooth at the small end will be greater, as shown by the lineh k; but if the bottom line of the tooth be made to converge to the…
