Testing my machine

              Results of measuring the force of the  handle=
              2 newtons, 2.50 newtons, 2.25 newtons
   
                 Results of measuring the force of brushing a dog=
              8.25 newtons, 8 newtons, 8.50 newtons
     

    I tested my machine by putting the hook of a spring scale around the lever. Then I started turning the lever to measure the force but using newtons. Then I measured the force by putting the spring scale hook around the brush then I started brushing a dog. My results show that using my machine is easier.
