Chapter 17, Problem 17.31P

Interpretation Introduction

Interpretation:

Specific strength of carbon nanotube (CNT) needs to be calculated and compared with the value in tableand the fraction of load carried by CNT fibers is to be determined.

Concept introduction:

Specific strength is defined as the ratio of tensile strength of component and density of component, the relation is stated as:

  $\text{Specific}\text{strength}\text{=}\frac{T{S}_{component}}{{\rho }_{component}}$

Where,

  $T{S}_{component}$ is the tensile strength of component.

  ${\rho }_{component}$ is the density of component.

Load carried by fiber is defined by relation,

  $\text{f}\text{=}\frac{{\text{F}}_{\text{f}}}{{\text{F}}_{\text{f}}\text{+}{\text{F}}_{\text{m}}}$

Where,

  ${\text{F}}_{\text{f}}$ is the force acting on the fiber.

  ${\text{F}}_m$ is the force acting on the matrix.
