Yerkes-Dobson law
An example of an intervening variable is stress, which can impact the relationship between hours of sleep and academic performance. In this case, stress mediates the relationship by influencing both the amount of sleep a person gets and their academic performance.

A scatter diagram with dots forming an upside-down U shape typically indicates a quadratic relationship between the variables being plotted. This suggests that as one variable increases, the other initially increases, reaches a maximum point, and then begins to decrease. It is important to further analyze the relationship to understand the underlying pattern and potential implications.
From the Hooke law, stress s is proportional to strain e; s = Ee where E is elastic modulus of the material; the stress is the bending stress which varies from plus on one surface to minus on the opposite surface.
Because our brains and body are so intertwined. Illness is a very common factor of stress and stress is a very common factor of illness. All said how do we stop this vicious cycle?
Some medications can seriously degraded pilot performance. Stress and fatigue can degrade performance as well.
Stress and overcome the lack of confidence and skills of a player and his proformance on the field, which is the result of lack of concentration and can cause injury.

Shear Stress divided by the Angle of Shear is equals to Shear Stress divided by Shear Strain which is also equals to a constant value known as the Shear Modulus. Shear Modulus is determined by the material of the object.
