Two gondolas on a ski lift are locked in the position shown in the figure while repairs are being made elsewhere. The distance between support towers is L= 30.5 m. The length of each cable segrnent under gondola weights WB = 2000 N and Wc- 2900 N are DAg = 3.7 mn, %3D DBC = 21.4 m, and DCD = 6.1 m. The cable sag at B is 3.9 ft and that at C is 2.3 m. The effective cross-sectional area of the cable is A =77 mm?. Which of the following nearly gives the tensile stress on cable AB?

Transcribed Image Text:Two gondolas on a ski lift are locked in the position shown in the
figure while repairs are being mnade elsewhere. The distance between
support towers is L- 30.5 m. The length of each cable segment under
gondola weights Wg = 2000 N and Wc- 2900N are DAB = 3.7 m.
DBC = 21.4 m, and DCD = 6.1 m. The cable sag at B is 3.9 ft and that
at C is 2.3 m. The effective cross-sectional area of the cable is A =77
mm. Which of the following nearly gives the tensile stress on cable
