Question 493General Subjects - Assistant Engineer

The correct answer is D) an audible click is heard and the handle releases. When using a micrometer torque wrench, the correct torque value is reached when the wrench produces an audible click and the handle releases, indicating that the desired torque setting has been achieved. This click and release mechanism is a key feature of torque wrenches, as it provides the user with clear feedback that the proper torque has been applied, helping to prevent over-tightening or damage to the components being worked on. The other options are incorrect because they do not accurately describe how a micrometer torque wrench indicates the correct torque value. A dial light on the handle (option A) or simply reading the dial (options B and C) do not provide the distinct audible and physical feedback that is characteristic of a properly calibrated and functioning torque wrench.
