Please explain how it can be solved. |

It's so easy. Simple calculation. Total pavement= 9m half = 9 * 0.5 = 4.5. Horizontal Distance ------------- Vertical Distance. 4.5m. --------------> 0.15m. 1 m. -------------->? 0.15 / 4.5. = 1/30. Means 1 in 30. |

Total width of carrige way = 9m. So camber always consider distance from crown to edge which is 4.5m here. Hence 4.5 ÷ 0.15 = 30, So camber is 1 in 30. |

The equation of straight camber:- y= W/2N. W - width of the road, N - slope, y- ht of camber(crown), 0.15=9/2N, N=9/2*0.15, N= 30. So camber is 1 in 30. |

Camber is given on half-width of the road. So, 9m/2=4.5m. Or 450cm. Now given that, For 450 cm long there is 15 cm height. 1 cm --- 15/450 = 1/30 or 1 in 30 =>answer. |

Ymax = W/2N. So, N = W/2 Ymax. N= 900/2*15 = 30. Gradient, G = 1 in N, G = 1 in 30. |

Thanks @Dabhi Deepak. |

A simple way is 450/15 = 30. Hence 1 in 30. |

Camber is ratio of height of crown to horizontal distance from centre to edge. So, first converting 15cm to m = 0.15, Camber = 0.15/4.5 = 1/30. |

camber in % will be (0.15/4.5) * 100 = 3.3 %. |

Slope = Rise/Fall. Slope = 0.15/4.5, Slope = 0.33, Hence, Slope = 1/30. |
