Chapter 14, Problem 14.31P

Interpretation Introduction

Interpretation:

The specific yield strengths of alloys like Al, Mg, Cu, Ti, and Ni by using densities of pure metals needs to be determined in ${\text{lb/in}}^3$. The order of calculated values needs to beexplained.

Concept Introduction:

The ratio of force per its unit area to the density of the same is called as specific strength of that material. It can also be described in strength to weight ratio or strength to mass ratio. The SI unit of specific strength is ${\text{Pa m}}^{\text{3}}\text{/kg}$ or $\text{N}\text{.m/kg}$.

This is significant to define any material for designing efficient and safe structures.
