Worked Solution & Example Answer:Describe two important properties of a material which is suitable for the manufacture of a prosthetic hand. - Leaving Cert Engineering - Question 1 - 2014
Step 1
Lightweight Material
Answer
A suitable material for a prosthetic hand should be light. This is crucial for comfort and usability, as a heavier prosthetic can lead to fatigue and difficulty in movement for the user. Lightweight materials, such as certain polymers or composites, allow for better maneuverability and ease of use.
Step 2
Strong and Durable
Answer
Another important property is that the material must be strong and durable. The prosthetic hand needs to withstand everyday wear and tear, providing adequate support for everyday tasks without breaking or deforming. Materials like carbon fiber or high-strength alloys can offer this needed strength while maintaining a reasonable weight.
