Which of the following statements is true regarding impact resistance?

1. Better supported materials are more impact resistant

2. Thickness has not affected impact resistance

3. Impact resistance does not change with the age of materials

4. Thinner materials are more impact resistant because they flex without breaking

The correct answer is: Better supported materials are more impact resistant

Impact resistance refers to the ability of a material to withstand sudden forces or impacts without being damaged. The statement that better supported materials are more impact resistant is accurate because when materials are better supported, they can absorb and distribute the force of an impact more effectively. This support can help reduce the stress experienced by the material upon impact, allowing it to resist damage or deformation. In contrast, the other statements do not hold true in understanding impact resistance. For instance, the notion that thickness has no effect on impact resistance contradicts the principle that thicker materials often provide enhanced protection against impacts. Additionally, the idea that impact resistance does not change with the age of materials overlooks the fact that many materials can become more brittle or weakened over time, thereby diminishing their impact resistance. Lastly, suggesting that thinner materials are somehow more impact resistant because they flex without breaking fails to recognize that while some thin materials may flex, they can often also be more prone to failure under significant impact. In general, thicker, well-supported materials tend to offer greater impact resistance due to their ability to absorb and distribute forces more effectively.
