Worm Wheel
Rotate the handle and lift the heavy mass suspended with the rope provided.
What did you observe?
It takes less effort to lift such a huge mass.
The science behind it :
Here, the worm and wheel arrangement gives the mechanical advantage in lifting the heavy mass. We gain more torque through worm and wheel arrangement. Torque is inversely proportional to speed. Hence, the lifting speed is low but the lifting capacity is high.
