The relationship between the alternating stress and mean stress is given by the following equation: σa=σe, where σe is the fatigue limit for completely reversed loading. The value of x for Gerber line is equal to _________

The relationship between the alternating stress and mean stress is given by the following equation: σa=σe, where σe is the fatigue limit for completely reversed loading. The value of x for Gerber line is equal to _________ Correct Answer 1-(σm/σu)x

The Gerber line follows the path of a parabola. So, if value of x is kept two, the equation satisfies the equation of the parabola.

The relationship between the alternating stress and mean stress is given by the following equation: σa= σe. The value of x for Goodman line is equal to _________
A plate with an elliptical hole in the centre, with semi-major axis (a) perpendicular to the direction of loading and semi-minor axis (b) along the direction of loading, is subjected to a pull P. The maximum stress induced at the edge of the hole is equal to (where $$\sigma $$ = Stress for a plate with no hole i.e. nominal stress)
Assertion (A): When there is an evidence of a linear relationship between two variables, it may not always mean an independent-dependent relationship between the two variables.
Reason (R): The casual relationship between the two variables may not imply a reasonable theoretical relationship between the two.
