An industrial roller door is a uniform rectangular panel made of a heavy material, y = 45 pcf, and rolls along the fixed rail D on its hanger-mounted wheels at A and B. The door is maintained in a vertical plane by the floor-mounted roller C which bears against the bottom edge. For the position shown, compute the horizontal side thrust (x-direction) on each of the wheels A and B that must be considered in designing the brackets. The door has a thickness, t = 2 in, and is made of solid material. a = 3 ft, b = 10 ft, c = 3 ft, d = 5 ft, e = 5 in T Detail of door hanger D La A b + C B 10'
