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
