She just balanced against 16 books, when these were fixed to the short end of the plank, but if she fixed them to the long end of the plank, she only needed 11 as balance. Now, what was the girl’s weight, if a book weighs equal to a three-quarter book and three-quarters of a pound? If she sat opposite to where the middle would be between the Short- and long end then I get 17.8 Pounds. If the girls is alone has to be sit in the short end of the teeteer, because she has to grab something in order to balance without falling, this is an assumption i guess, so she is equal to 16 books in weight. When she slides the books out to the long end of the plank, and then returns and sits on the short end of her side of the plank, only 11 books are required. So the distance from the fulcrum to the long-end is 1.4545 times the distance from the fulcrum to the short end, and these distances can be any amount that meets the ratio.
Also, we have to note that if she originally balanced against the 16 books at the short-end of the plank while she herself was sitting on the long-end of her side of the plank (poor depth perception?

We also haven’t accounted for the weight of the string used to tie the books to the plank. Hi guys- this problem comes from a puzzle book almost a century old, so that’s why the wording is a little strange. Its like you had to keep the same distance between the books and the girl, the only difference is the distance between the center of the teeter and the girl and the books, however i think the problems do not state that, the distance between could be more or less, but cool.
To balance, the (weight * distance) on one side of the pivot must equal the (weight * distance) on the other side, (as seen in RK’s equations above).

Indiana Pacers’ big man Roy Hibbert was out for a nice dinner on the town on Saturday night when this happened.
Hibbert and the Pacers are in New York for their series against the Knicks, meaning this likely is taking place in the Big Apple. However, she couldn’t find another child to play with her, so she tied some books to one end of the plank to balance her weight at the other.
