  1. What does a double-headed arrow symbol on a structural or mechanical drawing typically indicate?

    Answer: A dimension showing distance between two points

    Double-headed arrows with extension lines are the standard ASME method for indicating linear dimensions on engineering drawings.

  2. On a mechanical drawing, what does 'BOM' or 'BOL' refer to?

    Answer: Bill of Materials

    BOM stands for Bill of Materials, which is the structured list of all parts, quantities, and descriptions needed to assemble the product.

  3. A keyway shown on a shaft drawing is used to:

    Answer: Transmit torque between the shaft and a hub or gear

    A keyway is a slot cut into a shaft (and matching hub) that holds a key, which transmits rotational torque between the two components.

  4. In structural drawings, EQ spacing notation means:

    Answer: Equal spacing between repeated elements

    EQ (or EQUAL) indicates that the dimension spaces between multiple repeated elements are all identical, avoiding the need to dimension each space individually.

  5. What type of view is used on structural drawings to show the actual profile of a cross-section cut through a member?

    Answer: Section view

    A section view is created by passing a cutting plane through the object and showing the resulting cross-sectional shape with crosshatching.

  6. What does the abbreviation 'TYP' mean when placed next to a dimension on an engineering drawing?

    Answer: Typical — the same dimension applies to all similar features

    TYP (Typical) indicates that the noted dimension or feature is repeated identically throughout the drawing wherever similar features appear.
