The cross dial method uses 2 dials mounted ___________ across from each other.

The cross dial method is a precise technique used in alignment tasks, particularly in the industrial setting for aligning shafts and machinery. In this method, two dial indicators are placed directly across from each other, which is essential for measuring any misalignment between the two points.

When correctly positioned at 180 degrees from each other, the two dials can provide feedback on both horizontal and vertical misalignment simultaneously. This configuration allows for an accurate reading of the movement and helps in determining the amount and direction of any misalignment present.

Using a different angle, such as 90 degrees or 120 degrees, would not allow for the same level of accuracy in measurement because it would not effectively capture the full range of misalignment that might occur between the components being measured. The alignment readings would be limited, potentially leading to incomplete or inaccurate alignment adjustments.

Ultimately, the 180-degree configuration maximizes the effectiveness of the cross dial method, making it a standard practice for precise machinery alignment.
