D. All of these are correct

Answer :

Final answer:

Alignment of couplings can be achieved using various tools, including a dial indicator, straight edge, and micrometer. Each tool serves a unique purpose, making the answer 'All of these are correct'. Proper alignment is essential to ensure the efficient operation of machinery.


Explanation:

Instrument Used to Align Couplings

In mechanical engineering, aligning couplings is essential for ensuring that machinery operates smoothly and efficiently. The instrument primarily used for this purpose can vary, but commonly includes:

  • Dial Indicator: This precise measurement tool allows for accurate detection of misalignment by measuring the gap and variance in position. When attempting to align two shafts, the dial indicator shows any deviation in the specified alignment.
  • Straight Edge: A straight edge can help assess alignment visually, ensuring that the coupling faces are flush and correctly aligned. It’s a simple tool but can be effective for rough checks of alignment.
  • Micrometer: While not typically used for alignment per se, a micrometer can measure small distances accurately and can be employed to check the dimensions of components associated with the coupling setup.

In conclusion, the best answer to the question is that each instrument plays a role in the alignment process, and therefore, the most accurate choice is All of these are correct. Proper alignment is crucial to prevent wear, vibration, and eventual equipment failure.
