The "Giant Swing" at a county fair consists of a vertical central shaft with a number of horizontal arms attached at its upper end as shown in (Figure 1). Each arm supports a seat suspended from a 5.00-mm-long rod, the upper end of which is fastened to the arm at a point RRR = 1.80 mm from the central shaft. a)Make a free-body diagram of the seat, including the person in it.
