- Question 2 of 15
Road roughness is measured usingCorrectIncorrect
- Question 3 of 15
Which of the following errors can be eliminated by reciprocal measurements in differential leveling?
I Error due to earth’s curvature
II Error due to atmospheric refractionCorrectIncorrect
- Question 4 of 15
A symmetric frame PQR consists of two inclined members PQ and QR, connected at ‘Q’ with a rigid joint, and hinged at ‘P’ and ‘R’. The horizontal length PR is l. If a weight W is suspended at ‘Q’, the bending moment at ‘Q’ isCorrectIncorrect
- Question 5 of 15
Two soil specimens with identical geometric dimensions were subjected to falling head permeability tests in the laboratory under identical conditions. The fall of water head was measured after an identical time interval. The ratio of initial to final water heads for the test involving the first specimen was 1.25. If the coefficient of permeability of the second specimen is 5-times that of the first, the ratio of initial to final water heads in the test involving the second specimen isCorrectIncorrect
- Question 6 of 15
A layer of normally consolidated, saturated silty clay of 1 m thickness is subjected to one dimensional consolidation under a pressure increment of 20 kPa. The properties of the soil are: specific gravity = 2.7, natural moisture content = 45%, compression index = 0.45, and recompression index = 0.05. The initial average effective stress within the layer is 100 kPa.Assuming Terzaghi’s theory to be applicable, the primary consolidation settlement (rounded off to the nearest mm) isCorrectIncorrect

- Question 8 of 15
A two-lane urban road with one-way traffic has a maximum capacity of 1800 vehicles/hour. Under the jam condition, the average length occupied by the vehicles is 5.0 m. The speed versus density relationship is linear. For a traffic volume of 1000 vehicles/hour, the density (in vehicles/km) isCorrectIncorrect
- Question 9 of 15
The horizontal distance between two stations P and Q is 100 m. The vertical angles from P and Q to the top of a vertical tower at T are 3 degree and 5 degree above horizontal, respectively. The vertical angles from P and Q to the base of the tower are 0.1 degree and 0.5 degree below horizontal, respectively. Stations P, Q and the tower are in the same vertical plane with P and Q being on the same side of T. Neglecting earth’s curvature and atmospheric refraction, the height (in m) of the tower isCorrectIncorrect
