After gauge placement, which action ensures the rod contacts the hole?

Pull the gauge gently to the side so the rod comes in contact with the hole Leave the gauge in the center Push the gauge deeper Remove gauge and rod

Correct Answer:

Pull the gauge gently to the side so the rod comes in contact with the hole

Explanation:

The key idea is to make sure the rod actually touches the hole by aligning the gauge with a slight lateral adjustment. When you place the gauge, the rod may not line up with the hole if kept centered, so gently pulling the gauge to the side lets the rod come into contact with the hole’s edge or opening. This alignment ensures the measurement reflects the real clearance or contact condition. Leaving the gauge in the center often results in no contact, while pushing deeper can misalign or damage the setup, and removing both parts ends the check. So a slight, careful shift to the side is the correct step to establish contact.
