outdoor exercise machine shown operating in Figure 1 requires the user to pull on the upper bar at nt A defined in Figure 2. This upper bar, ABC, rotates about the pin at point B. The pivot rotation beam CD upwards, causing beam EDG to rise, lifting the person in the seat. For this problem, you only be analyzing the middle picture in Figure 1. The simplified model for this picture is shown in re 2. Note, all members are connected by pins, shown in black. = 20 lb and Fash=150 lb, calculate the following: A) The force in member HI (12 points) B) The force in member CD (12 points) c) The reaction forces at pin B (6 points) b) Describe how the exercise machine user could change their body position to reduce the force in member Hl. Explain why.
