Civil Engineering Highway Engineering Difficulty: Medium

Time required to stop a car moving with a velocity 20 m/sec within a distance of 40 m, is A four wheel truck or whose operating weight is 12000 kg is pulled along a road having a rising slope of 2% at a uniform speed. Assume grade resistance factor = 10 kg/tonne. The tension in the tow cable is 720 kg. The rolling resistance of the road will be $${\frac{3}{4}^{{\text{th}}}}$$ or $${\frac{1}{4}^{{\text{th}}}}$$ extra space is left in sewer pipes at maximum discharge for The rise and fall method To determine the discharge at a section in a stream from its rating curve, the required data are i) slope of water surface at the section ii) stage at the section iii) current meter readings at the section The correct answer is
