Airport runways are generally designed with a buffer zone around 300 mm long beyond the runway end, to accommodate aircraft that land too fast or too far down the runway and go off the end. Where that's not possible, airports are increasingly installing so-called Engineered Material Arresting Systems (EMAS) to prevent runaway aircraft from entering nearby roads, neighborhoods, or waterways. One such system, at New York's JFK airport, consists of a 132-mm-long bed of crushable cement blocks. What average force must this system exert on a 55-MgMg jetliner that enters the arrestor bed at 37 m/sm/s if the jet is to stop 100 mm into the bed

Please solve this question. Subject: Transportation engineering Fillet Radius Problem (Airport Engineering) Determine the minimum lead-in and the radius of the fillet (and compare with recommended values) to maintain the cockpit over the centerline for an aircraft with a 110.3 ft wingspan, a wheelbase of 40.5 ft, undercarriage width of 25.5 ft, and the distance between the main undercarriage and cockpit equal to 50.4 ft. The aircraft is moving between two parallel taxiways through a connecting taxiway which has a centerline perpendicular to the parallel taxiway. With a wingspan of 110.3 ft this aircraft is in airplane design group III (see table 6- 2). From Table 6-23 and Table 6-18, the taxiway width is 50 ft, the minimum safety margin is 10 ft, the recommended centerline radius is 100 ft.

VERY URGENT!!! The distance between stations A and B on a railway route is 40 km andelevation 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 andThis 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 straightresistance wo = 2 + (V2/ 4000) kg/t.
