State the correct relationship based on the straight line drawn
For a straight line with negative gradient passing with y-axis interception,
Thickness is increase linearly to force
o Position of eye must be perpendicular to the scale of the micrometer screw gaugeto avoid parallax error
o Avoid over tightening the aluminium sheet by using the rachet.
