A 24kg chimpanzee hangs from the end of a horizontal, broken branch of length L0 = 1.4m , as shown in the figure(Figure 1) . The branch is a uniform cylinder 4.7cm in diameter, and the end of the branch supporting the chimp sags downward through a vertical distance ?x = 14cm.
What is the shear modulus for this branch? (S=? N/m^2)
