Deviation on a plane is a measure of how much a surface deviates from a flat plane. It is important in many applications, such as manufacturing, engineering, and surveying. There are several methods for finding deviation on a plane, including using a straight edge, a level, or a laser level.
One common method for finding deviation on a plane is to use a straight edge. Place the straight edge on the surface and look for any gaps between the straight edge and the surface. The size of the gaps will indicate the amount of deviation. Another method for finding deviation on a plane is to use a level. Place the level on the surface and check the bubble. If the bubble is centered, the surface is level. If the bubble is not centered, the surface is not level and the amount of deviation can be determined by the angle of the bubble.
