A rock climber, 69.0 kg, dimbs along a fissure with is hands pushed against one side of the fissure and his feet against the other as shown in the figure. The width w of the fissure is 1.26 m and the man's center of mass is at distance x 0.756 m from the right wall of the fissure. The coefficient of static friction between his hands and rock is P - 0.720 and between his feet and rock is uz- 1.19. Assume he is just at the point of slipping on both surfaces, he likes to live dangerously.

A rock climber, 69.0 kg, dimbs along a fissure with is hands pushed against one side of the fissure and his feet against the other as shown in the figure. The width w of the fissure is 1.26 m and the man's center of mass is at distance x= 0.756 m from the night wall of the fissure. The coefficient of static friction between his hands and rock is p - 0.720 and between his feet and rock is uz - 1.19. Assume he is just at the point of slipping on both surfaces, he likes to live dangerously. What is the least honzontal push by the hands and feet that will keep the man stable? 354 N You are correct.
