Question 3 of 10 < > -/1 E : The figure shows a 80 kg climber hanging by only the crimp hold of one hand on the edge of a shallow horizontal ledge in a rock wall. (The fingers are pressed down to gain purchase.) Her feet touch the rock wall at distance H = 2.1 m directly below her crimped fingers but do not provide any support. Her center of mass is distance a = 0.15 m from the wall. Assume that the force from the ledge supporting her fingers is equally shared by the four fingers. What are the values of the (a) horizontal component F and (b) vertical component Fy of the force on each fingertip? com. - (a) Number Units (b) Number Units e Textbook and Media
