The tangent modulus of the initial, linear portion of a stress-strain curve is called Young's modulus.

The plot comprises two linear portions meeting at a critical chain length c.

To locate T g, the linear portions are extrapolated and intersect at the point which is taken to be the characteristic transition temperature of the material.

The broad linear portion is yellowish brown, containing a narrow dark greenish mass of frass.

The relationship between inductance and AL number in the linear portion of the magnetisation curve is defined to be:

The slope of the linear portion of this curve is then found using the method of least squares.

The linear portion is brown, while the blotch portion is whitish to whitish-green and semitransparent.

The mine is almost transparent even in the early linear portion.

The frass is blackish and is deposited in a line in the linear portion of the mine.

This is represented in the plot by the increasing linear portion of the curve.
