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 19 n, wts= 11 n, wt= 4 n, du= 12 cm, de = 40 cm, dh 9. which of the three segments in problem 8 creates the largest torque about the shoulder when the arm is horizontally extended? explain your answer and discuss the implications for positioning the arm for shoulder-level tasks. 64 cm. ( 308 n)
