NCCER Millwright Practice Exam

Anchor bolts must be aligned to which reference point?

1. The center of gravity

2. The anchor plate

3. The equipment center line

4. The nearest wall

The correct answer is: The equipment center line

Aligning anchor bolts to the equipment center line is essential for ensuring that the machinery or equipment is properly positioned and functions as intended. The equipment center line serves as a critical reference point that helps maintain balance, stability, and alignment of the equipment during operation. Proper alignment with the center line prevents undue stress and potential failure of components due to misalignment, thereby extending the lifespan of both the equipment and the installation. In millwright work, ensuring that the equipment is centered allows for the correct distribution of forces and weight, which is crucial for safe and efficient operation. This alignment also facilitates easier access for maintenance and reduces the risk of vibrations that can arise from improper setup. The other reference points listed—such as the center of gravity, anchor plate, or nearest wall—do not provide the same level of stability and operational significance, which is why the equipment center line is the best choice for aligning anchor bolts.
