- This climber (mass=52kg) is maintaining this posture while grabbing onto a rock at P3 and reaching for the wall with her right hand (no contact of wall and right hand). The rock at P1 applies a force of 187.4N at an angle of 140.2 deg from the positive x axis on her right foot at P1. The rock at P2 and the climber's pants have a coefficient of static friction of 0.78 and the y component of the force of the rock on her pants is 144.0 N upward. The rocks at P1 and P2 are vertical surfaces. The friction forces acting at P1 and P2 are as large as friction will allow. Analyze the forces in the frontal plane as shown and show mechanical rationale for each question. a) What is the net interaction of the her left hand on the rock at P3? b) Which surface (P1 or P2) has a lower coefficient of static friction? If she took off her shoes and tried to hold this position with her socks (coefficient of static friction of her socks and rock is 0.78), will she be able to maintain static equilibrium?
