The 64.5-kg climber in is supported in the “chimney” by the friction forces exerted on his shoes and back. the static coefficients of friction between his shoes and the wall, and between his back and the wall, are 0.80 and 0.64, respectively. assume the walls are vertical and that the static friction forces are both at their maximum. ignore his grip on the rope. determine the minimum normal force he must exert.
