Chapter 6, Problem 6.57P

Interpretation Introduction

(a)

Interpretation:

The Brinell hardness number of the steel plate needs to be determined.

Concept Introduction:

Brinell hardness number of metal can be calcualated as follows:

$HB=\frac{2F}{\pi D[D-(\sqrt{D^2}-\sqrt{I^2})]}$

Here, F= Force applied

D = Diameter of indenter

I= Indentation

Interpretation Introduction

(b)

Interpretation:

The tensile strength of the steel plate needs to be determined.

Concept Introduction:

Tensile strength is the resistance offered by a material to break under tension.

Tensile strength = 500HB
