A technician uses forces to bend a straight metal strip. After the forces are removed, the strip remains curved.
Which conclusion about the metal strip is correct?
Its deformation is elastic because bending changed its shape.
Its deformation is elastic because it is stationary after release.
Its deformation is inelastic because it did not regain its original shape.
It was not deformed because its resultant force is now zero.
