Problem 17PE

Consider the 52.0-kg mountain climber in Figure 5.22. (a) Find the tension in the rope and the force that the mountain climber must exert with her feet on the vertical rock face to remain stationary. Assume that the force is exerted parallel to her legs. Also, assume negligible force exerted by her arms. (b) What is the minimum coefficient of friction between her shoes and the cliff?

Solution

Step 1 of Step 5

We have to find tension in the rope as she climbs the mountain with her feet and she should remain stationary on vertical direction with her feet. The free body diagram is given below.
