The Rube Goldberg Machine: The Yummi Nummies

The Rube Goldberg Machine that my group and I made is called the “Yummi Nummies”. This invention of ours is significant because it helps solves the problem of having to feed pets. It can be used for many different animals in need of being fed. For example, Yummi Nummies can be very productive in zoos. This machine can shrink the chance of a zookeeper from getting hurt if he were to bring in the food to a wild animal’s cage. This machine is not simply only used for zoos, this machine can also help everyday people feed their pets they have at home. That was originally why we made this machine, to allow people to feed their animals with just one motion. No matter what animal it is or how much animals you have, this machine can benefit you. This
The first thing that you must do is to drop a marble inside the pulley machine. When the marble has dropped into the pulley, the side of the pulley with more force will go down and the one with the least weight will go up. The pully starts out with potential energy, however it changes to kinetic energy because of the force of the marble. The weight of the marble makes the pulley change its position. When the side with more force of the pulley fell towards the ground, it tapped the wheel and axel, and the wheel and axle began spinning. The wheel and axel’s spinning gently triggers the toy car in potential energy to travel down the inclined plane and change into kinetic energy. As quickly as the car fell, it stopped right in front of the lever. The lever has potential energy and it is there to prevent the car from going on and on. When the car stops at the lever, the car pushes the lever with a little bit of force, which triggers the marble to roll out into our second pulley. Our second pulley works similarly to our first pulley. The input force is where the marble falls in and the output force is when the other bucket falls down because of the movement. In this last stage, where the food comes out, the pulley with the heavier weight in it goes down about evenly to the food side of the bucket. The food side of the bucket tilts and all the food rolls down the inclined plane. It rolls down and lands into the food tray, and
All that is required of the person is to drop a marble into the first bucket so that everything can be triggered. In this simple machine, there are 5 different types of simple machines. Each one has different purposes. For example, the inclined planes in our machine allowed objects to roll down a slanted platform more easily than a straight platform. The wheel and axle and pulleys were used to trigger different objects. In our machine, the wedge and lever is used to hold things up. The wedge’s purpose was to allow the inclined planes to stay up in the right position. The lever was used to hold up the car; it prevented the car from continuously running down. Our machine is also very simple to run, even though when you explain it in words it sounds really complicated. This machine has many triggers to start many parts of the machine so that the machine can run smoothly. Overall, our machine was a
