Ques 54 Structural Analysis

The plane truss shown in the figure has 13 joints and 22 members. The truss is made of a homogeneous, prismatic, linearly elastic material. All members have identical axial rigidity. A to M indicate the joints of the truss. The truss has pin supports at joints A and L and roller support at joint K. The truss is subjected to a 10 kN vertically downward force at joint H and a 10 kN horizontal force in the rightward direction at joint B as shown.

Ques 57 Surveying

Among the following statements relating the fundamental lines of a transit theodolite, which one is CORRECT?

Ques 58 Surveying

A map is prepared with a scale of 1:1000 and a contour interval of 1 m. If the distance between two adjacent contours on the map is 10 mm, the slope of the ground between the adjacent contours is _______.

Ques 59 Surveying

A bird is resting on a point P at a height of 8 m above the Mean Sea Level (MSL). Upon hearing a loud noise, the bird flies parallel to the ground surface and reaches a point Q which is located at a height of 3 m above MSL. The ground surface has a falling gradient of 1 in 2. Ignoring the effects of curvature and refraction, the horizontal distance (in meters) between points P and Q is _______. (in integer).

Ques 60 Transportation Engineering

A car is travelling at a speed of 60 km/hr on a section of a National Highway having a downward gradient of 2%. The driver of the car suddenly observes a stopped vehicle on the car path at a distance 130 m ahead, and applies brake. If the brake efficiency is 60%, coefficient of friction is 0.7, driver's reaction time is 2.5 s, and acceleration due to gravity is 9.81 m/s², the distance (in meters) required by the driver to bring the car to a safe stop lies in the range _______.

Ques 61 Transportation Engineering

Ques 62 Transportation Engineering

The free mean speed is 60 km/hr on a given road. The average space headway at jam density on this road is 8 m. For a linear speed-density relationship, the maximum flow (in veh/hr/lane) expected on the road is _______.

Ques 63 Transportation Engineering

The number of trains and their corresponding speeds for a curved Broad Gauge section with 437 m radius, are 20 trains travel at a speed of 40 km/hr, 15 trains travel at a speed of 50 km/hr, 12 trains travel at a speed of 60 km/hr, 8 trains travel at a speed of 70 km/hr, and 3 trains travel at a speed of 80 km/hr.

Ques 64 Transportation Engineering

The figure presents the trajectories of six vehicles within a time-space domain. The number in the parentheses represents unique identification of each vehicle. The mean speed (in km/hr) of the vehicles in the entire time-space domain is _______. (rounded off to the nearest integer).

Ques 65 Transportation Engineering

The following data is obtained from an axle load survey at a site:
Average rear axle load = 12000 kg and Number of commercial vehicles = 800 per day. The pavement at this site would be reconstructed over a period of 5 years from the date of survey. The design life of the reconstructed pavement is 15 years. Use the standard axle load as 8160 kg and the annual average vehicle growth rate as 4.0%.
Assume that Equivalent Wheel Load Factor (EWLF) and Vehicle Damage Factor (VDF) are equal. The cumulative standard axle (in msa) for the pavement design is _______. (rounded off to 2 decimal places).
