Read through the full deck, or practise recalling each answer above.

  1. Why do materials or components in a product need reinforcing or stiffening?

    Show answer

    So they can withstand the forces and stresses acting on them in use without bending, deforming or failing.

  2. Why does triangulation make a frame structure rigid?

    Show answer

    A triangle cannot change shape without changing the length of a side, so adding diagonal members turns a frame into rigid triangles that resist distortion under load.

  3. Adding diagonal bracing so a frame is made up of rigid triangles is called ?.

    Show answer

    triangulation

  4. What is boning in a textile product?

    Show answer

    Stiff strips (e.g. plastic or steel) inserted into sewn channels in a garment to hold its shape and give it structure, as in a corset or bodice.

  5. What is a dart in textile construction?

    Show answer

    A folded wedge of fabric stitched into a garment to give it a fitted, three-dimensional shape that holds its form.

  6. How does layering improve the structural integrity of a textile product?

    Show answer

    Using several layers of fabric (or adding interfacing) makes the material stiffer and stronger than a single layer.

  7. Name three textile techniques used to give a product structural integrity.

    Show answer

    Boning, darts and layering.

  8. What is the purpose of plastic webbing in a moulded plastic part?

    Show answer

    Thin ribs or webs moulded into the part stiffen it and resist bending without greatly increasing the amount of material or weight.

  9. Thin moulded ribs that stiffen a plastic product with little extra material are known as plastic ?.

    Show answer

    webbing

  10. What does reinforcing a product mean?

    Show answer

    Adding extra material or components to a weak or highly stressed area so it can carry greater forces without failing.
