Contents of a mechanical working drawing package A complete set of mechanical working drawings for a product typically includes which of the following items?

Introduction / Context:
Working drawings must allow a product to be manufactured, assembled, and inspected. This requires component-level detail, assembly-level visualization, and administrative data that links items to procurement and quality systems.

Given Data / Assumptions:

• Part details define geometry, tolerances, and materials.
• Assemblies (often including an exploded view) clarify fit and fasteners.
• The parts list ties item numbers to orderable components and quantities.

Concept / Approach:
Combining detailed parts, assembly views, and a BOM ensures traceability from concept to shop floor. Exploded views improve clarity of assembly order and fastener placement, while detailed drawings guide machining or fabrication.

Step-by-Step Solution:

Verification / Alternative check:
Perform a build trial or digital mock-up to ensure the drawing package alone is sufficient to assemble the product without additional tribal knowledge.

Why Other Options Are Wrong:
Each individual item is necessary for completeness; therefore, “all of the above” is correct.

Common Pitfalls:
Missing hardware callouts or incomplete BOM entries cause delays and assembly errors.

Final Answer:
all of the above
