A candidate has excellent strength but cannot be produced in the component's required shape. How should it be treated during material selection?

  1. A

    Keep every material with strong performance because manufacturing can be considered after the material is selected.

  2. B

    Rank materials by purchase cost before checking whether they can be made in the required shape.

  3. C

    Exclude a material that cannot be produced in the required shape, even if it has excellent strength.

  4. D

    Accept a material that meets the function even if the proposed process cannot produce it reliably.

Which approaches can help make trade-offs between feasible material candidates explicit? Select all that apply.

  1. A

    Use weighted scoring, with criteria scores and importance weights visible.

  2. B

    Set acceptable boundaries for properties such as cost, mass, or service life.

  3. C

    Choose the candidate with the highest score while keeping the criteria and weights undisclosed.

  4. D

    Use Pareto comparison to identify alternatives where improving one goal would worsen another.

True or false: If a material has a lower environmental impact per kilogram, a product made from it will necessarily have a lower total environmental impact.

  1. A

    True

  1. A

    ρE\frac{\rho}{E}

  2. B

    Eρ\frac{E}{\rho}

  3. C

    EρE\rho

  4. D

    E+ρE + \rho

Before releasing a material-and-process choice, which checks support validation of the actual design? Select all that apply.

  1. A

    Confirm that the chosen grade and condition are available.

  2. B

    Assume a shortlisted option is validated without checking whether the process can achieve the required properties.

  3. C

    Check that the proposed process can achieve the required dimensions and properties.

  4. D

    Confirm that relevant joining, inspection, and surface-treatment methods are viable.

In material selection, what does a Pareto comparison identify?

  1. A

    A set of candidates that all meet the maximum strength requirement.

  2. B

    A ranking that identifies one material as universally best.

  3. C

    A set of alternatives where improving one goal would worsen another.

  4. D

    A list of candidates ordered only by material density.

12
True or false
1 point

True or false: For the support-bracket example, the best final choice is necessarily the option with the lowest density or the highest strength.

  1. A

    True

  2. B

    False

A support bracket must carry a known load, fit a fixed space, resist outdoor exposure, and be produced in several thousand units. Describe a defensible sequence for selecting and validating a material-and-process option, including how you would compare feasible candidates and account for life-cycle impacts.

A designer records the loads and their duration, the temperature range, exposure to moisture or chemicals, wear, production volume, maintenance access, and consequences of failure. What design term describes these operating circumstances?

15

A component must meet a minimum strength requirement, and the design team wants to reduce its mass as much as possible. Which category best describes reducing the mass?

  1. A

    A constraint, because it must be minimized

  2. B

    An objective, because it is a quality to improve

  3. C

    A free variable, because the designer can choose it directly

  4. D

    A service condition, because it describes how the part operates

A part must meet a specified corrosion-resistance limit. Several candidates fail that mandatory limit, while others pass it. What should the designer do before comparing candidates by cost?

  1. A

    Keep every candidate and rank them only by purchase cost

  2. B

    Average each candidate's strength and corrosion performance

  3. C

    Eliminate candidates that fail the corrosion requirement before ranking the survivors

  4. D

    Replace the corrosion requirement with a preference for lower mass

A designer can change a component's shape, dimensions, and surface treatment to meet its requirements. What category describes these choices?

A proposed manufacturing route may change a material's properties and may not work with every candidate. How should a design team handle material and process selection?

  1. A

    Choose the material and process together because the process can limit material options or alter properties

  2. B

    Select the material first and disregard the process until production begins

  3. C

    Choose the process only after ranking materials by strength

  4. D

    Treat process selection as unrelated to whether the finished part meets its requirements

A team uses weighted scoring to rank feasible materials for a design with competing priorities. Which practice makes the result's basis clear?

  1. A

    Hide the scores and weights so the final ranking appears impartial

  2. B

    Use identical weights for all criteria without regard to their importance

  3. C

    Show the scores and weights that reflect the agreed importance of each criterion

  4. D

    Use weighted scoring only after removing every trade-off between criteria

A team is comparing two materials for a product expected to provide a required service over many years. Which approach gives the most consistent basis for comparing their environmental impacts?

  1. A

    Compare the impact of providing the required service for the same specified period

  2. B

    Compare only the impact per kilogram of each raw material

  3. C

    Compare the materials at purchase and ignore maintenance and replacement

  4. D

    Compare each alternative using whichever life-cycle stages are most favorable to it
