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.
The higher the number of repetitions you can actually perform with the chosen weight, the larger the error in the estimate of your 1-RM. 1-RM = (weight lifted)/[1.0278 â (repetitions x 0.0278)]. From: Brzycki, M. (1993). Strength testing-Predicting a one-rep max from a reps-to-fatigue.Journal of Physical Education, Recreation and Dance 64 (1) , 88-90. This relationship is based on the relatively linear relationship between repetition maximal scores and the percentage of the 1-RM. properly conducted maximum strength test will however be more accurate than the predicted strength from an equation. Endurance versus Strength The correlation between absolute strength and endurance has been reported to exceed 0.90 (de Vries, 1980; Invergo et. al., 1991).
