Trial 1 - Designing and building a compound machine

1. Observe the drawing to drop a weight through a net. This is a sample of a Rube Goldberg Machine that uses cartoons to show the most elaborate and ridiculous devices to accomplish the most ordinary tasks. Beside each number write the name of the simple machine used in this compound machine.

2. Here is your chance to be creative, and a little wacky too! You are challenged to create a compound gadget that starts a ball above the ground (or table top), moves the ball to the ground, and then moves the ball to the same height. The ball that moves back up can be a different ball. The trick is that you must use:

   1. 2 inclined planes
   2. 2 levers
   3. 1 pulley
   4. force sensor to measure force anywhere in the process

3. Sketch out your design in a set of blueprints with the Draw tool. Refer to Technical Hints to create a drawing. Only common everyday items (string, cardboard, tape, wooden sticks, etc.) should be used in your blueprints.
   
   

4. Share your blueprints and materials list with your instructor.

5. With your instructor's approval, construct your compound gadget.
