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
