    • D.

      Stretching

    Correct Answer
    C. Shrinking
    Explanation
    Shrinking is the hand forming operation that refers to the reduction of an area of a piece of metal. This process involves applying pressure or force to a specific area of the metal, causing it to contract and reduce in size. This can be done using various tools and techniques, such as hammering or using a shrinking disc. Shrinking is commonly used in metalworking to shape and manipulate metal pieces, particularly when creating curves or contours. It allows for precise control over the metal's shape and can be used to achieve desired dimensions and aesthetics.

    011 if you need to add additional crimps to shrink  a form angle you place them

    • A.

      In the location of the original crimps

    • B.

      On the ends of the formed angle.

    • C.

      Between the original crimps

    • D.

      In the middle of the angle

    Correct Answer
    C. Between the original crimps
    Explanation
    When adding additional crimps to shrink a form angle, they should be placed between the original crimps. This is because the original crimps are already in place and serve as the starting point for the angle. By adding the additional crimps between the original ones, the angle can be further tightened and secured. Placing the crimps in the location of the original ones or on the ends of the formed angle would not effectively shrink the angle.

    011 When forming a flange by shrinking you start hammering on an angle at

    • A.

      Either end,working quickly to the other .

    • B.

      Either end,working gradually to the other.

    • C.

      The center,working quickly towards both ends.

    • D.

      The center,working gradually towards both ends.

    Correct Answer
    D. The center,working gradually towards both ends.
    Explanation
    When forming a flange by shrinking, it is best to start hammering on an angle at the center and gradually work towards both ends. This method allows for even and controlled shrinking of the material, ensuring that the flange is formed properly without any distortions or unevenness. Working gradually towards both ends also helps to distribute the hammering force evenly, preventing any potential damage or deformation to the material. This technique is preferred over working quickly, as it gives the metal more time to adjust and avoids any sudden changes that could lead to errors in the flange formation.

    • B.

      Buckle at the outside edges

    • C.

      Remain smooth at the inside bend

    • D.

      Remain smooth at the outside edges

    Correct Answer
    A. Buckle at the end
    Explanation
    When hand forming an angle by shrinking the flange, the flange tends to buckle at the end. This means that the material on the flange will wrinkle or fold up towards the end of the angle being formed. This can happen due to the uneven distribution of stress and strain on the material during the shrinking process. The buckling at the end is a common occurrence when hand forming angles by shrinking flanges.

    Correct Answer
    C. Buckle
    Explanation
    If the material is not held flat against the face of the form during the bumping process, it will buckle. This means that the material will bend or fold out of shape, creating a noticeable bulge or wave-like appearance. This can happen when there is not enough pressure or support applied to the material, causing it to warp or deform. Buckling can affect the overall quality and appearance of the material, making it important to ensure that it is held flat during the bumping process.

    • A.

      100

    • B.

      180

    • C.

      400

    • D.

      600

    Correct Answer
    C. 400
    Explanation
    To properly remove oxidation from the bare metal of a machine surface, a grit of 400 sandpaper should be used. This grit is considered fine and is suitable for gently removing the oxidation without causing damage to the metal surface. Using a coarser grit may be too abrasive and result in scratches or further damage to the metal, while a finer grit may not be effective enough to remove the oxidation. Therefore, 400 grit sandpaper is the appropriate choice for this task.
