Mechanical properties are those properties that involve a reaction to an applied force.
True
False
Allows material to return to its original form after it is deformed
elasticity
plasticity
Allows a material to be deformed without breaking, but the material doesn´t return no its original form
elasticity
plasticity
Like some metals, are not easily deformed by an applied force
flexible materials
hard materials
soft materials
strong materials
Rigid materials
Like some plastics, rubber and textiles, exhibit the opposite property
Rigid materials
flexible materials
hard materials
soft materials
Strong materials
Like ceramics, concrete and some metals, are not easily deformed when a force is applied
rigid materials
flexible materials
hard materials
soft materials
strong materials
Like we clay, exhibit the opposite property
ridid materials
flexible materials
soft materials
strong materials
hard materials
Like leather and rubber, have a wide elastic or plastic range or both. Not break easily.
Rigid materials
flexible materials
hard materials
soft materials
strong materials
like paper, exhibit the opposite under a small amount of force
weak materials
tough materials
Like some metals, show the opposite behaviour
weak materials
tough materials
those properties depend on the physics of the material, including desity, thermal and electrical conductivity, and thermal expansion
