Quarter 2, Blogpost #3

So this is supposed to be last weekends blogpost, but I forgot to do one and was distracted ALL week by spirit week so I haven't gotten around to doing it until today. But anyway, this picture relates back to what we've been learning in Unit 4 about forces. We just recently took our Unit 4 exam and on the exam was this problem, "A 50 kg gymnast hangs vertically from a pair of parallel rings (one in each hand). If the ropes supporting the rings are attached to the ceiling directly above, what is the tension of each rope?" This problem can also be paired with the picture above of our plastic bag holder. Although the bag is attached to one rope rather than two ropes, it is similar because in both cases only one weight is being used. In the problem, the two ropes share the weight of the gymnast. In the picture, to one rope shares the weight of the bag. The answer to the problem was 250 N, because the weight of the gymnast was being split between the two ropes, creating the even tension. The rope or strap in the picture above would also have one tension (sort of like how the example problem had an equal tension) because when you have "one rope" you get "one tension".
