qualsthat ratio, and from the point where it cuts the arc, as b, drop a vertical,ba. Ma and ba will be the radii required. Using Burmesters diagram the author has devised an algebraic solutionof the problem (Indust. Eng., June, 1910) which leads to the followingequations: Let L— distance between… … Fig. 170. If rt is given, r2 = Vi.25 L2 - (0.79057 L -If the ratio r2 -=- rx is given, let r2/rx = c: r2 : r0 + n)2 - = CTx. 0.79057 L + r0. We then have a + cr-i = v.fi!2— (a + ri)2, which reduces to (1 + c2) rx2 + 2 a (1 + c) n = 1.25 L2 - 2 a2, a quadratic equation, inwhich a = 0.79057 L — r0.…
