Question 214General Subjects - Assistant Engineer

The correct answer is D) malleability. Malleability is the ability of a metal to be hammered, rolled, or pressed into thin sheets without breaking. This property is important for metals that need to be shaped or formed into various products. Ductility, on the other hand, refers to the ability of a metal to be drawn into a wire without breaking. The other options are incorrect: Elasticity is the ability of a material to deform under stress and then return to its original shape, fusibility is the ability of a material to melt and fuse together, and these properties are not directly related to the ability to be hammered or rolled into thin sheets.
