ommontangent at C, the pointof compound curvature,are in the same straight line. Continue the curve p AC to D, where its tan- fig. itt. gent OD becomes parallel to BK, and consequently the radiusED parallel to FB, Then if the chords CD and CB bedrawn, we have the angle CFD = CFB, whence BCD, the… … 366. To find a limit in one direction of each radius of acompound curve. Let AI and BI, Fig. 177, be the tangents of the curve ; drawIM bisecting the angle AIB ; draw ^X and ^il/perpendicularrespectively to AI and BI, meeting IM in L and M. Then theradius of the branch commencing on the shorter…
