Your Work

1. Find out what mechanical advantage means.
2. Use three examples, for each, describe the mechanical advantages it provides AND explain what happens when the distance between the fulcrum and the effort changes. For example, what is the mechanical advantage of a wheelbarrow? What happens when the person who pushes the wheelbarrow holds the wheelbarrow’s handles closer to the load?
3. Once complete, upload your work to 8.4 Practical Mechanisms - SRD Work on www.bournetolearn.com (it is the last badge in the topic).
