-Use to simple machines to draw a Rube Goldberg Machine
 * Purpose** - Learn the machanical advantages of various simple machines - lever, pulley and incline plains.

1. Make the three different class levers. Measure the input and output forces at two different distances for each one.
 * Procedure**

2. Make three different pulley set ups. Measure the input and output forces. Count the number of ropes supporting the weight

3. Measure the input and output forces of three different ramp heights.


 * Data:**
 * Machine || Type || Input force (N) || Output force (N) || Input distance (m) || Output distance (m) || AMA || IMA || Efficiency ||
 * Lever || 1 ||  ||   ||   ||   ||   ||   ||   ||
 * || 2 ||  ||   ||   ||   ||   ||   ||   ||
 * || 3 ||  ||   ||   ||   ||   ||   ||   ||
 * Pulley || 1 pulley ||  ||   ||   ||   ||   ||   ||   ||
 * || 2 pulleys ||  ||   ||   ||   ||   ||   ||   ||
 * || 3+ pulleys ||  ||   ||   ||   ||   ||   ||   ||
 * Incline Plane || Height- ||  ||   ||   ||   ||   ||   ||   ||
 * || Height- ||  ||   ||   ||   ||   ||   ||   ||
 * || Height- ||  ||   ||   ||   ||   ||   ||   ||


 * Calculations**

Calculate the IMA, AMA and efficiency of each of the levers, pulleys and incline plans.

Draw each set-up.
 * Questions**

Instead of the regular conclusion, create a drawing of a Rube Goldberg Machine* to do a simple job. It must be made using each of the simple machines. (Screw, Incline plane, pulley, wheel or cog, lever, wedge)
 * Conclusion (25 pts)**

18 pts - Uses 3 machines 20 pts - 4 machines 22 pts - 5 machines 25 pts - 6 machines


 * For 55 years Goldberg's award-winning cartoons satirized machines and gadgets which he saw as excessive. His cartoons combined simple machines and common household items to create complex, wacky, and diabolically logical machines that accomplished mundane and trivial tasks. His inventions became so widely known that Webster's Dictionary added "rube goldberg" to its listing, defining it as "accomplishing by extremely complex, roundabout means what seemingly could be done simply.
