Question

calculate a angel of banking for a surface of radius 200m with a safest speed of 40 km / hr use g= 9.8 m/ s.also calculate the lower speed limit for the coefficient of friction of the surface as 0.4us​

Answer 1

Calculate a angel of banking for a surface of radius 200m with a safest speed of 40 km / hr use g= 9.8 m/ s.also calculate the lower speed limit for the coefficient of friction of the surface as 0.4us .

Angel of banking for a surface of radius = 200m

Speed = 40 km / hr

g= 9.8 m/sec

Calculate the lower speed limit for the coefficient of friction of the surface

______________________

Angle of banking

tan¶ = v² / rg

v = 40×5/18

tanQ = (200/18)²/200×9.8

tanQ = 2000/31752

= 0.06
