    2. To view an image in the provided list, select its name.
    3. Choose Select for the background image you want and to return to the bending moment answer box.

      The name of the image and a thumbnail appear to the right of Background image.

  2. Select Edit Answer next to the Correct Answer box in the item.

    The workspace appears with the background image applied.

  3. Position the background image and grid.
