Common mistake
Misunderstanding Density
Students often confuse low density with lightweight materials, thinking all low-density materials are weak or fragile.
Emphasize that low density refers to the mass per unit volume and does not necessarily indicate strength; aluminium alloys can be both low density and strong.
