No 11 characteristics ExplainationMethod of moving lawnmover

- Push the handle

- Bigger force produced

Mass of lawnmower

- Big

- To increase the stability

Size of cutter blade

- Big size of cutter blade

- Increase the cutting area of cutting

grass

The angle between handle and the

horizontal

- large

- Force exerted to the ground bigger

- Therefore, I choose lawnmover M,

- because it has push handle, big mass of lawnmower, big size of cutter blade

and has large angle between handle and horizontal line
