Mechanical systems often require a combination of mechanisms to complete a given task. Any time two or more machines are combined, the result is a compound machine. If many mechanisms are combined, the machine may even be referred to as a complex machine. Compound machines can range in complexity from a crane or automobile to a simple manual can opener. A bicycle is an example of a compound machine. The pedals, brakes, handle bars, and sprocket systems are just some of the mechanisms on most bicycles. In this activity you will work in teams to design and build a compound machine to accomplish an instructor-specified task.
1. The inclined plane. The numbers were easy to work with and rather small
2.The wheel and axle. It was hard to get the measurements that we wanted and the numbers were really small.
3.5 pounds input and 3 out put. We used a weight and the output would be slightly less than the input.
4. Add another pulley for efficiency.
