Question
Last 3 digit of id =030
d) A 7-degree curve branches off a 3 degrees main curve in an opposite direction in the
layout of a B.G. yard. If the speed on the branch line is restricted to (25+Z) kmph,
determine the speed restriction on the mainline. Assume permissible deficiency in can't
as 76 mm. [Here, Z = last three digit of student ID x 0.05 (if student ID =
17.02.03.140, then Z = 140 x 0.05 = 7)]. N.B. In the case of fractional values, write at
least up to 3 decimal places.
