Optimization

Optimization comes from the same root as "optimal". "Optimal" means the highest. When you do the optimization process, that is when you are "making it best" to maximize everything and to achieve optimal results, a set of parameters is the base for the se…

Integration

Integration means to sum the things. In mathematics, it is the branch of Calculus which is used to find the area under the curve. The operation subtraction is the inverse of addition, division is the inverse of multiplication. In the same way, integratio…

Application of Integration

In mathematics, the process of integration is used to compute complex area related problems. With the application of integration, solving area related problems, whether they are a curve, or a curve between lines, can be done easily.

Volume

In mathematics, we describe the term volume as a quantity that can express the total space that an object occupies at any point in time. Usually, volumes can only be calculated for 3-dimensional objects. By 3-dimensional or 3D objects, we mean objects th…

Area

Area refers to the amount of space a figure encloses and the number of square units that cover a shape. It is two-dimensional and is measured in square units.

Textbook Question

Chapter 2, Problem 35P

The modulus of elasticity (E ) is a measure of a materialâ€™s resistance to deformation: the larger the modulus, the stiffer the material. During fabrication of a ceramic material from a powder form, pores were generated that affect the strength of the material. The magnitude of elasticity is related to volume fraction porosity P by

E = 304 ( 1 − 1.9 P + 0.9 P 2 ) . (2.76)

(a) If a porous sample of silicon nitride has a modulus of elasticity of E = 209 GPa. obtain the quadratic equation for volume fraction porosity P. (b) Solve the quadratic equation found in part (a) using both the methods of completing the square and the quadratic formula.

(c) Repeat parts (a) and (h) to find the volume fraction porosity of a silicon nitride sample with a modulus of elasticity of 25 GPa.
