Question

Find the angle of banking of a railway track of radius of curvature 2800m, if there is no side thrust on the rails for a train running at 126 Km/hr.​

Answer 1

Answer:

here is your answer

Explanation:

Fnet,y = n cos - w = 0

n cos = w

n = w / cos

Fnet,x = n sin

Fc = m v2 / r

Fc = Fnet,x

substituting, this provides

Fc = mv 2 / r = n sin = [w / cos ] sin

Fc = mv 2 / r = w [ sin / cos ]

Fc = mv 2 / r = w tan

m v 2 / r = m g tan

tan = v 2 / g r
