Engineering Challenge: Ping Pong Ball Seperator?
A friend of mine who teaches in Ireland gave this problem a number of his students of Design Industrial, and some of the results were very smart. You have to build a ping pong separator that separates a 20 ping pong balls into two equal groups of ten. Only can be powered by gravity. Mechanisms are well advanced, while not being able, in addition to gravity is used to run them. One thing is, of course, have limited materials. 1 18x24 sheet of construction paper. (As a triple thick printer paper) 1 24x32 sheet of cardboard 1 meter tape 30 paper clips, small regular size, not oversized. Infinite Balls Elmer's glue is dispensed from a hopper overhead, and the proposal falling, rolling, whatever, must be sufficient to start and the power of your machine. The best design gets better answer, of course. Ties go to the first position. Good Luck.
Since pp balls that are all equal, not be separated by size or any other characteristic. You can not count on them. Would drop on the board, roll, guided by parts of the ship at an intersection of Y. At the Y, which is down a path, filling a pocket. When you have 10 balls pp pocket it blocks the leg of the Y, forcing balls after taking the other road. The only problem I have is how to suppress pp bounce balls when dropped and hit the board.
