HOW FRICTION HELPS
Lift the solids fitted here one by one.
The science behind it :
The solids have almost equal weight but different shapes and structure. While lifting, the friction between your hand and the solid varies with its shape and texture. When the surface is rough and the shape permits better hold, the friction is more and we can raise it easily. If the solid is of fine texture and slippery shape, the friction is less and we have to put more effort in lifting the solid.
