Exercise 3

Using the diagram in Sample Problem 7.1 as a model, calculate the tension required in the deltoid with a moment arm of 3 cm from the shoulder, given the following weights and moment arms for the upper arm (u), forearm (f), and hand (h) segments: wt u = 19 N, wt f = 11 N, wt h = 4 N, d u = 12 cm, d f = 40 cm, d h = 64 cm.
