No 11 –2010 characteristics ExplainationMethod of moving lawnmover-Push the handle
- Bigger force produced
Mass of lawnmower -Big
- More stable // cut efficiently
Size of cutter blade-Big size of cutter blade
- Cut more more grass
The angle between handle and the horizontal-large
- Bigger downward force // not lift up
- 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
