Answer 1

Answer:

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.

Answer 2

Answer:

Replace the wheelbarrow with a plank with one end on the ground.

Place the load L at 1/2 the distance to the other end and lift the other end at the length of the plank. So you only lift a weight of L/2. The wheel also supports a weight of L/2.
