Bear Barrow

February 26, 2013

Build a wheelbarrow to carry bears.

Use a scale to measure the force on the handle when the bears are in the middle, near the handle, and near the wheels.
Where can you place the bears so they will be the easiest to move?

Here are some heavy weights.

Holding them near the handle is hard work but when they are near the wheels it is easy.
