Q1) A man is pulling a spring of stiffness coefficient 8 Ib/in by his hand with the entire arm held horizontally rotating about shoulder joint O; this force acts at the 21° angle is shown. Determine the force exerted by the deltoid muscle on the upper arm at A and x- and y- components of the force reaction at the shoulder joint. The weight of the upper arm Wu = 4.1 Ib, the weight of the lower arm W1 2.4 Ib, and the weight of the hand WH= 0.9 Ib; all these weights act at the locations shown in the figure. the spring extended 1 in only as shown in figure 1. A tensile force in the deltoid muscle prevents the arm from A- 8 Ibin Equilibrium x-1 in Deltoid muscle Fo A YW, YW -5.2 16.5 25.4 Figure 1
