72 THE SLIDE RULE 3438 X 100 762. 7 81 50' X 100 730 / = 450' = 7 30', = 1090 feet, or P. T. Y is at station 10 + 90 on the branch track.
Problem 31. Using the same curves for the branch and " Y" tracks as in No. 30, but having Fig. 31 a 60 central angle for the branch curve and the P. T. Of "Y" coming beyond the P. T. Of the branch and on the tangent to the branch curve at its P. T. , find the P. C. On the main track and the P. T. On the branch track for the "Y" curve.
