Materials Selection & properties

When selecting materials, a designer has to take into consideration how the product will be used, and where it will be used. They must be aware of the stress that the product will be under when it is in use to find the right materials for the job.

• True

• False

Properties are the unique characteristics of a material

• True

• False

Why must you consider the availability of a material?

• because the cost of the materials must fall within a budget

• because sourcing materials locally will help reduce transport costs and supporting the local economy .

• because some materials may be more suitable for mass manufacturing.

• because the ability to recycle or reuse materials varies.
