Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Imagine you need to select a plastic for a safety shield in a sports arena. Discuss how you would consider tensile strength, impact resistance, and creep in your decision-making.

💡 Hint: Focus on the type of forces and stresses that the shield would face.

Challenge 2 Hard

Evaluate a scenario where a plastic beam is used in constructing a load-bearing ceiling. Discuss the implications of creep on its longevity.

💡 Hint: Consider how long-term loading can affect materials.
