A motor-cyclist moving with a velocity of 72 kmh1 on a flat road takes a turnat a point where the radius of curvature of the road is 20 m. In order to avoidsliding, he must not bend with respect to the vertical by an angle e greaterthan (g 10 ms-2):(a) tan-16(c) tam 25.92(b) tan 12(d) tam14

Answer»

We know ,tanةµ = v^2/(r*g) < where v= velocity of motorcycle, r= radius of the curvature & g= acceleration due to gravity>tanةµ= 20^2/(20*10)tanةµ=2ةµ=tan−1 (2)
