The diagram to the left is a shelf connected to the wall by a fixed (cantilever) support. On the shelf is a stack of books, a goldfish bowl, and a vase. The books have a vertical force of 18 N at A, the goldfish bowl has a vertical force of 36 N at B, and the vase has a vertical force of 4 N at C; the shelf supports all the weight of the books, goldfish bowl, and vase. The shelf is 10 inches long. a. Draw O free body diagram of the system. b. What is the sum of all three forces (R)? c. What is x for the line of action of R? d. If a hanging plant were to be added exerting a vertical force of 2 N at C, what would the new x² be?
