Chapter 6, Problem 6.48P

Interpretation Introduction

(a)

Interpretation:

The force should be determined for the given block of silicon carbide causing a fracture in it.

Concept Introduction:

The ratio of strength and stress in deformation is known as Flexural Modulus.

We can determine the flexural modulus with the help of below-mentioned formula:

$E_{bend}=\frac{{\text{L}}^3\text{F}}{4{\text{ wh}}^3\delta }$

In the abovementioned formula,

• F = the fracture
• L= the distance between the two points
• w = width of the specimen
• h = height of the specimen
• $\delta$ = the deflection

Interpretation Introduction

(b)

Interpretation:

The flexural strength of the given block of silicon carbide should be determined.

Concept Introduction:

The ability of any specimen to undergo deformation under the influence of load is known as a Flexural strength.

We can determine the flexural strength with the help of below-mentioned formula:

${\sigma }_{Bend}=\frac{3\text{FL}}{2{\text{wh}}^2}$

In the above-mentioned formula,

• F = the fracture
• L= the distance between the two points
• w = width of the specimen
• h = height of the specimen
