Question

A train runs along a unloaked circular of radius 30m at a speed of 54km the mass of train 10^6what is centipetal force​

Answer 1

Answer:

# Given-

r = 30

v = 54 km/h = 15 m/s

m = 106 kg

# Solution-

a) Here, centripetal force is provided by the lateral thrust of the rail on the wheel. The reaction force here causes wear and rear of the rail.

b) Angle of banking -

Angle of banking is given by,

tanθ = v^2/rg

tanθ = 152/(30×10)

tanθ = 225/300

tanθ = 0.75

Taking inverse,

θ = tan-1 (0.75)

θ = 36.87°

Therefore, the angle of banking should be 36.87° to prevent wear and tear of tyres.
