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.
How BMI Is Calculated. BMI is a ratio of weight and height and is calculated using a formula. To calculate BMI, take an individual's weight in pounds and divide it by the square of her height in inches.Multiply that result by 703.So someone who weighs 140 pounds and is 5 feet 6 inches tall would have a BMI of about 22.6.MI is a ratio of weight and height and is calculated using a formula. To calculate BMI, take an individual's weight in pounds and divide it by the square of her height in inches.
