They are both because the lever is where u hold on to the wheelbarrow and the inclined plane is the are where it hold things
A wheel barrow has tow levers (the handles), a wheel and axle (wheel), and some people could say it is an inclined plane BUT only when it is rolling and it is tilted ti be an incline plane. When it is not moving it is a flat plane not an inclined plane. :)
a hatchet is a inclined plane
A ramp is an inclined plane because an inclined plane is a set of a surface set at an angle that is not a right angle. In which a ramp is an inclined plane!
The thread running around the screw is an inclined plane. If you were to straighten it out, it would be an inclined plane. The screw itself can be considered a combination of wedge and inclined plane.
