1. The wheelbarrow's wheel and axle help the wheelbarrow to move without friction thus making it easier to push or pull. That's why it will be easier to lift a load in wheel barrow of the load is transferred towards the wheel.

2. In order to cut the metals we need more energy and effort. If the effort distance is greater than load distance there will be magnification of force and the metals would easily could cut.So the blade of a metal cutter shorter than that of scissors used by tailors.

3.A lever is a simple machine and can be moved to move a load (or do work). Effort is applied to one part of the lever and it pushes the load at another part. Using a lever makes it easier to move a load and so you use less effort. ... 2) Second Class Lever -- the load is between the fulcrum and the effort.
