The distance between theoretical nose of crossing and actual nose of crossing for practical purposes, is
A)Nose thickness x tan ?
B)Nose thickness x cot ?
C)Nose thickness x sin ?
D)Nose thickness x cos ?

Question

Quizplus · Accepted Answer

The distance between the theoretical nose of crossing and the actual nose of crossing for practical purposes is calculated using the formula involving the cotangent of the angle, which is given by "Nose thickness x cot ?". This is because the cotangent function relates the thickness of the nose to the horizontal distance from the theoretical to the actual nose, considering the geometry of the crossing.
