Studies have shown that the traffic flow on a two-lane road adjacent to a school can be described by the Greenshields model. A length of 0.5 mi adjacent to a school is described as a school zone (see the figure) and operates for a period of 30 min just before the start of school and just after the close of school. The posted speed limit for the school zone during its operation is 15 mi/h. Data collected at the site
when the school zone is not in operation show that the jam density and mean free speed for each lane are 136 veh/mi and 63 mi/h. If the demand flow on the highway at the times of operation of the school zone is 90% of the capacity of the highway, determine the following.
0.5 mile

(b) the number of vehicles affected by the school zone during this 30-minute operation…

- A cylindrical container of internal diameter and height H =200 mm is filled with concrete asshown in the figure below. Beginning at room temperature (T = 20oC), the temperature isdecreased until the concrete develops internal tensile stress that may results in crack (as shown inthe figure on the right below). This is due to the thermal shrinkage of the concrete and strongadhesion between the concrete and the walls of the container. D = 100 mmDetermine the temperature at which the concrete develops a tensile crack.Hint: Assume that the concrete remains linearly elastic until failure.Information about concrete:E = 30 GPa (Young’s Modulus)ν = 0.2 (Poisson’s Ratio)α = 12 ·10-6mm/mm/ oC (Coefficient of thermal expansion)(σt)max = 3 MPa (tensile strength)arrow_forwardI will rate, thanks!arrow_forward1- Present worth analysis An Environmental engineer is considering two materials for use in a sustainable building.
