Which term describes the ability to bend and return to shape?

• A. Elasticity
• B. Ductility
• C. Malleability
• D. Durability

Answer: (A)

Elasticity describes the ability to bend and then return to the original shape. When a material is loaded, it can deform, but if you stay within its elastic limit, once the load is removed it springs back to its initial dimensions. That’s why a metal spring or a rubber band returns to shape after a small bend. If you push beyond the elastic limit, the deformation becomes permanent and the material behaves plastically. Ductility is about drawing into wires, malleability about hammering into sheets, and durability about resisting wear over time.
