Mechanical Properties Which object would be better for a tug of war?

Mechanical Properties Hardness This is a material’s ability to resist denting and scratching.

Mechanical Properties Ductility The ability of an object to stretch without breaking.

Mechanical Properties Elasticity The ability of an object to return to its original shape.

Mechanical Properties Malleability The ability of a material to be flattened or bent without breaking.

Mechanical Properties Resilience A material’s ability to resist shock without breaking.

Mechanical Properties Stiffness A material’s ability to maintain its shape.

Mechanical Properties Tensile Strength A material’s ability to resist tension without breaking or deforming.

Some additional properties to think about: Resistance to corrosion: This means the material will not rust in the presence of fumes, water, salt, etc. Electrical conductivity: This means electrons can flow through it Thermal conductivity: Does it conduct heat?
