The zipline is intended to carry 2 people. Your calculation (check) is when the people are at the lowest point of the zipline (as shown in Figure ). At this point, they have come to rest at the bottom of the hill and the cable to the right and left of the running gear is 7.5° to the horizontal as shown. Your calculation will only consider this static scenario. 

a. Describe how the participants' weight is passed from the harness to the zipline cable. Treat the running gear as a single point and at rest.

b. Complete the free body diagram of the running gear for the scenario shown in Figure.

c. If the maximum combined mass of the participants, the seat assembly and the running gear permitted is 250 kg and the right-hand cable is at 7.5° to the horizontal and the left-hand cable is at 7.5° to the horizontal, what are the forces (to three significant figures) in the cable? Take g= 9.81 m/s ^-2
