No 11 – characteristics Explaination
Method 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
