Problem 2. Determine the joint load (FJ) and tensile force in the deltoid muscle (FD) created by holding a 5 kg weight (W) in an outstretched arm. Also include the weight of the arm (W1), which is 40 N. Also, write you answer as a percentage of total body weight (170 lbs). Hint: For equilibrium of linear forces, you could draw the force vectors as the sides of a right triangle. 7,1 mit -60cm 20 cm d=5 cm
