Question

29 sep conduct an investigation unbend a paper clip such that you have a long, straight piece of metal. bend one of the initially straight sections back and forth several times. does it become easier or harder to bend the paper clip in the same spot? what happens if you keep bending the paper clip back and forth?

Explanation:

Bending the paper clip repeatedly in the same spot causes metal fatigue—microscopic cracks form and grow, weakening the metal. This makes it easier to bend over time. Continuing to bend eventually causes the cracks to connect, leading to the paper clip breaking.

Answer:

It becomes easier to bend the paper clip in the same spot; if you keep bending it back and forth, the paper clip will break.
