As students continue their investigation of Simple Machines, we have started looking at how simple machines can work together. When two or more simple machines are present in a device, the device is classified as a compound machine. We learned that a skateboard is a compound machine. It has four wheels and two axles. The board itself works like a lever in order for the rider to do stunts and tricks.
Here is a short video clip we watched in class from Dr. Skateboard’s Action Science series on Simple Machines.
