Chapter 12, Problem 50CP

In the What If? section of Example 12.2, let d represent the distance in meters between the person and the hinge at the left end of the beam. (a) Show that the cable tension is given by T = 93.9d + 125, with T in newtons. (b) Show that the direction angle θ of the hinge force is described by

tan θ = ( 32 3 d + 4 1 ) tan 53.0 °

(c) Show that the magnitude of the hinge force is given by

R = 8.82 × 10 3 d 2 9.65 × 10 4 d + 4.96 × 10 5

(d) Describe how the changes in T, θ, and R as d increases differ from one another.
