Electric Field Strength is defined in many books as F/Q, where F is force and Q is the test charge. but why is that? why not F/(2Q)? or F/Q^2?, is this word "strength" related to stress-strength as in mechanics?

An electric field is a physical quantity that describes the influence that charged particles have on each other. It is a vector quantity, meaning it has both magnitude and direction.
Electric field strength is a measure of the intensity of an electric field at a given point. It is defined as the force per unit charge experienced by a point charge placed at that point.
Electric field strength is calculated by dividing the force exerted on a point charge by the magnitude of the charge. It can also be calculated by dividing the voltage difference between two points by the distance between those points.
The unit of electric field strength is newtons per coulomb (N/C). This represents the amount of force exerted on a unit charge in an electric field.
The strength of an electric field decreases as the distance from the charge increases. This relationship follows an inverse square law, meaning that doubling the distance from the charge will result in the electric field strength being reduced by a factor of four.
