A primary runway is being designed for a new airport to serve airport approach category B. As part of this work it is required to design two con- secutive vertical curves (a crest vertical curve followed by a sag vertical curve) to be located midway along the length of the runway. The design should satisfy all the grade and minimum length requirements.
If conditions are such that the crest vertical curve connect grades of +.5% and +1.5%, determine all the properties of both curves that will be necessary to set out the curves. The elevation and station of the point of intersection of the two tangents of the crest vertical curve are 556.50ft and 595+45.00, respectively, and the distance between the points of intersections of the vertical curves is 975ft.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct
