Question

A motorcycle is travelling at 30 metre per second on the circular road of radius 300 find its inclination with the vertical and the coefficient of friction between the tyres and road

Answer 1

The inclination with the vertical is 17° and Co-efficient of friction between the tyres and the road is 0.305

1) when a motorcycle is taking a turn in a curved path, its angle of inclination is given by

tan θ = v^2 / rg

where v = velocity of the bike, r = radius of curvature, g = acceleration due to gravity.

2) So, using the formula and putting the given values

tan θ = 0.305 = μ (co efficient of friction)

3) So, θ = 17.00°
