Wheel and Axle and a Lever.
The whole of the wheelbarrow is the level, with the wheel being the fulcrum.
Most devices are combinations of the seven "simple machines". Specifically, a wheelbarrow combines the wheel with the lever.
A wheel barrow is a simple machine because it is made up of two or more simple machines. A wheel and axle, and a lever.
What simple machine is the wheel based on? What do we call the “fulcrum” of a wheel?
puuley and lever
That would be a Second Class Lever. An example is a Wheel Barrow. The wheel axle is the fulcrum, the handles and Bin are the lever, and of course the load is in the bin.
There are three types of lever, with examples as follows: A seesaw (teetertotter) is a Class 1 lever A wheel barrow is a Class 2 lever A pair of scissors is a Class 3 lever
wheel and axle and screw
A wheelbarrow is considered a class 2 lever, where the load (the items being carried) is between the effort (the force applied to lift the handles) and the fulcrum (the wheel).
