Examples of third -class levers would be spoons, shovels, and baseball bats. The mechanical advantage is always less than 1. The order would be load, effort, and then fulcrum.
Why is a spoon a first class lever?
When you use a spoon to prise a lid from a tin you are using a simple machine called a lever. ... By having the fulcrum (the rim of the tin) close to the lid (the load) a larger force can be applied to the load to open the tin . By this means you are reducing the effort required, this is what first class levers do best.
