we choose this complex machine cause we origanly wanted pulley as are simple machine but we didnt get to so we got wedge we disided we would combian the two to make are complex machine.we hope you enjoyed to see are project.sadly you can not use are project cause it breaks easly.
for are demo we tied a home made door wedge to a string and then put the door wedge under a door it held the door in place when we pulled the string the wedge came out and the door closed.are object of this demo was to allow people in wheel chairs to use door wedges.
