Which of the following tools can be used for dimensional inspection of a bearing in a rocker arm?

• A. Laser scanner
• B. Telescope gauge and micrometer
• C. Digital caliper and scale
• D. Optical comparator

Answer: (B)

The choice of a telescope gauge and micrometer for dimensional inspection of a bearing in a rocker arm is particularly suitable because these tools are designed to provide precise measurements of internal and external dimensions. A telescope gauge is specialized for measuring the bore or inside diameter of holes, such as those found in bearings, ensuring accuracy through its ability to reach into the component and gauge the internal dimensions directly. Micrometers, on the other hand, are widely recognized for their capability to achieve high-resolution measurements, typically in the range of thousandths of an inch. Together, these tools allow for meticulous measurement of bearing dimensions, which is critical to ensure proper fit and function within the rocker arm assembly. This combination is particularly effective in manufacturing and quality control settings where precise measurements are essential to maintaining performance standards in mechanical components. While other options might be capable of measuring dimensions, they may not offer the same level of accuracy or specificity needed for inspecting a bearing.
