The distance between stations A and B on a railway route is 40 km and elevation difference is 400 meters. The total length of the line segment between these two stations is 5 km. There are tunnels with a radius of 1400 meters and tunnels with a total length of 2 km. tunnel and This slope is detrimental for a train going down the slope at 100 km/h in a section where the victim overlaps. Is it harmless? Tunnel resistance 3 kg/t, curve resistance 700/R kg/t, straight and straight resistance wo = 2 + (V2/ 4000) kg/t.

Civil Analysis of highway section A portion of a four-lane multilane highway with a full median carries 2,600 vehicles per hour during peak hours in the busiest direction. In the traffic flow, there are 2% RVs and 14% trucks. The facility's regular users are mainly motorists. The segment under study is a mile-long, 3% sustained gradient. PHF equals 0.88. Field research has been done to establish that the facility's free-flow speed is 55.0 miles per hour. What degree of service will be provided during peak hours at this facility?

2. The flow that has velocity field V = 3txī – t²yj + xzk a) Determine the type of flow (considering dimensionality and steadiness), b) At the point (x, y, z)=(0, -2, 1), find total acceleration vector, c) Determine the volumetric dilatation rate.
