A EXAM #2 IE 3477 Methods and Industrial Engineering March 11, 2021 1. (20 points total) A guard rail at the front row of the second deck of a sports stadium is 85 cm. high. When someone sits back normally in a seat with a seat back in that section, the angle between the eye and the near edge of the playing field is 35 degrees below horizontal. The height of the seat was designed based on an average male. Assume that the horizontal distance from the eyes of a person seating to the edge of the guard rail is 1.15 mts. Determine what percentage of the female population may be able to see the near edge of the playing field over the rail. ANSWER:
