For the 2D truss with the applied loads shown below, the strain energy in the member XY is _______ kN-m. For member XY, assume AE = 30 kN where A is cross-section area and E is the modulus of elasticity.

Ques 59 Transportation Engineering

The penetration value of a bitumen sample tested at 25°C is 80. When this sample is heated to 60°C and tested again, the needle of the penetration test apparatus penetrates the bitumen sample by d mm. The value of d CANNOT be less than _______ mm.

Ques 60 Transportation Engineering

Which of the following statements CANNOT be used to describe free flow speed (u_f) of a traffic stream?

Ques 61 Transportation Engineering

The acceleration-time relationship for a vehicle subjected to non-uniform acceleration is,
dv/dt = (α - βv₀)e^-βt
where, v is the speed in m/s, t is the time in s, α and β are parameters, and v₀ is the initial speed in m/s. If the accelerating behavior of a vehicle, whose driver intends to overtake a slow moving vehicle ahead, is described as,
dv/dt = (α - βv)
Considering α = 2 m/s², β = 0.05 s^-1, and dv/dt = 1.3 m/s² at t = 3 s, the distance (in m) travelled by the vehicle in 35 s is _______.

Ques 62 Transportation Engineering

On a circular curve, the rate of superelevation is e. While negotiating the curve a vehicle comes to a stop. It is seen that the stopped vehicle does not slide inwards (in the radial direction). The coefficient of side friction is f. Which of the following is true:

Ques 63 Transportation Engineering

A sign is required to be put up asking drivers to slow down to 30 km/h before entering Zone Y (see figure). On this road, vehicles require 174 m to slow down to 30 km/h (the distance of 174 m includes the distance travelled during the perception-reaction time of drivers). The sign can be read by 6/6 vision drivers from a distance of 48 m. The sign is placed at a distance of x m from the start of Zone Y so that even a 6/9 vision driver can slow down to 30 km/h before entering the zone. The minimum value of x is _______ m.
