Literary and artistic naturalism aims at accuracy and objectivity and cultivates realistic and even sordid portrayals of people and their environment. Philosophical naturalism, which is often identified with materialism, holds that minds, spirits, and ideas are fundamentally material.
For the stiffness to weight ratio, see specific modulus. The specific strength is a material's strength (force per unit area at failure) divided by its density. It is also known as the strength-to-weight ratio or strength/weight ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa /(kg / m 3), or N Â·m/kg, which is dimensionally equivalent to m 2 /s 2, though the latter form is rarely used.
Ratio Scale of Measurement. The ratio scale of measurement satisfies all four of the properties of measurement: identity, magnitude, equal intervals, and a minimum value of zero. The weight of an object would be an example of a ratio scale. Each value on the weight scale has a unique meaning, weights can be rank ordered, units along the weight scale are equal to one another, and the scale has a minimum value of zero.
