A 70.0 kg climber 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 0.760 and 0.610, respectively. What is the minimum normal force he must exert? Assume the walls are vertical and that friction forces are both at a maximum.
