Here is the front view of our mechanism. It has a chain belt that is attached to the wheel and axle. we put the smaller gear at the top because it will bring a much greater mechanical advantage. If we would of put the bigger gear on top it would have no mechanical advantage. For every one time the big wheel spins the small gear would have spun twice as much which make it have a great mechanical advantage. If the wheel and gear were the same size they would have a spin ratio of 1:1.

In this image you cant see it but a gear shares a axle with the bottom of the chain belt. This will help with mechanical advantage. For one time that the chain belt spins the gear would have spun several times. That gear is right next to another gear that is smaller. These gear has the string that will pull the counter weight. As the other weight falls the wheel will spin the chain belt. Then the gear that shares the axle with the belt will spin. They will all work together to spin the gear with the string on it. The string will roll on the gear which will pull the weight. The incline plane will help lift it. We are gonna pull more distance to get more effort. At the end it carried 500 grams with 200 grams .

This is the side view of our final design.
We are using a wheel and axle with string
to hold our effort force. We are also using
string to pull our resistance force. The resistance
force will clime the incline plane. This might not
be a good idea since the metal causes friction which
will affect our mechanical advantage.
