Name the property according to its definition.
- the property of regaining the original dimensions upon removal of the external load.
- the property of breaking without warning.
- a combination of a number of physical and mechanical properties.
- a point on the stress - strain curve at which the stress levels off or actually decreases while strain continues.
- the capacity of a metal to be permanently deformed in tension without breaking.
- the property of resistance to external loads or stresses without incurring structural damage.
- the property of a metal which permits permanent deformation by compression without rupture.
Make up definitions out of these words and name the property.
separation, another, atoms, a resistance, or, or, of, to, rotation, one, about compression.
which, permanent, a metal, the property, of, deformation, without, by, compression, rupture, permits.
mechanical, a number, a combination, properties, of, of, and, physical.
before, absorbing, the property, fracture, considerable, of, energy.
due to, within, load, deformation, a body, which, an, applied, the force, externally, resists.
