Evaluate the use of expanded polystyrene as a material in the manufacture of cycling helmets, as shown. - Leaving Cert Engineering - Question 2 - 2016

Expanded polystyrene is a lightweight plastic material that is easily moulded, making it suitable for various applications, including cycling helmets. Its properties allow it to be shaped into intricate and attractive aerodynamic designs, which contribute to the aesthetic appeal of the helmets.

Additionally, expanded polystyrene has excellent impact absorption capabilities. It is designed to absorb significant forces during impact, which can be crucial for protecting a cyclist's head in case of accidents. The material is warm to the touch, which enhances comfort when worn against the skin during rides.

Moreover, its lightweight characteristic prevents adding extra weight to the helmet, ensuring that cyclists can wear it comfortably for extended periods. Overall, the combination of these attributes makes expanded polystyrene an effective and advantageous material choice for the manufacture of cycling helmets.
