What Makes a Good Wheelbarrow?

Aim:

I am going to investigate what makes a good wheelbarrow by substituting the wheelbarrow for a metre rule and some 10g weights.

Levers

There are three types of different levers. There are:

Type 1:

These levers have the fulcrum between the moving force (effort) and the load.

Type 2:

The load is between the fulcrum and the moving force. These levers act as force magnifiers.

Type 3:

The moving force (effort) is between the load and the fulcrum. These levers act as distance magnifiers. A person using a fishing rod can draw in the line for long distances using small movements of the arm.

The above information was obtained from the Learn UK website.

Variables:

I am going to test two variables to see what affects the effort needed to lift the wheelbarrow. I can do this because the sum of the clockwise moments = the sum of the anti-clockwise moments.

First of all what needs to be said is, that it will be possible to change more than one thing on the wheelbarrow which in practical terms
