11 12 A A A 68.5 kg mountain climber is rappelling down a steep mountain face. Her foot makes contact with the rock at point A. Her rope attaches to her harness at point B, which is located at x1 = 0.719 m and y1 = 0.478 m relative to point A. Her center of gravity is found at point C, which has an x coordinate x2 = 1.37 m relative to point A. -x1 T Ꮎ B A X2 The rope makes an angle of 53.1°. W Calculate the tension in the rope. Round to the nearest Newton. HINT: Four forces are acting on the mountaineer: friction, normal force, weight, and tension. A well-chosen pivot point will simplify the torque equilibrium equation, as any forces applied at the chosen point will create no torque about the pivot. Which of A, B, or C, removes unknown/unwanted forces?
