A curved circular road track has a radius of curvature r. For a vehicle traveling at speed v, what is the ideal angle of banking (θ) required so that no lateral frictional force is needed between tires and road?

tan θ = v² / (r * g) tan θ = (r * g) / v² sin θ = v / (r * g) cos θ = v² / (r * g)

Correct Answer:

tan θ = v² / (r * g)
