Answer :
Final answer:
Dial test indicators can measure angular or parallel misalignment between shaft centers or couplings, essential in ensuring machinery components are aligned correctly. Therefore, the correct answer is c. Angular, parallel.
Explanation:
Dial test indicators, when set up with proper mounting brackets, can be used to check the relationships of either angular or parallel misalignment between the shaft centers or couplings.
These precision instruments are used in mechanical engineering to measure small distances and angles, which is critical for the proper alignment of machinery components.
Angular misalignment refers to the difference in the inclination of one shaft relative to another, while parallel misalignment indicates that the shafts are offset from each other in a parallel direction but not co-linear.
When set up with proper mounting brackets, dial test indicators can be used to check the relationships of angular misalignment between the shaft centers or couplings.
