PROBLEM 12.53
Tilting trains, such as the American Flyer, which will run from
Washington to New York and Boston, are designed to travel safely
at high speeds on curved sections of track, which were built for
slower, conventional trains. As it enters a curve, each car is tilted
by hydraulic actuators mounted on its trucks. The tilting feature of
the cars also increases passenger comfort by eliminating or greatly
reducing the side force F, (parallel to the floor of the car) to which
passengers feel subjected. For a train traveling at 160 km/h on a
curved section of track banked through an angle = 6° and with a
rated speed of 100 km/h, determine (a) the magnitude of the side
force felt by a passenger of weight W in a standard car with no
tilt (= 0), (b) the required angle of tilt ø if the passenger is to feel
no side force. (See Sample Problem 12.6 for the definition of rated
speed.)
