Chapter 8, Problem 8.87DP

Interpretation Introduction

(a)

Interpretation:

The methods used to manufacture paper clips needs to be explained.

Concept Introduction:

1. Paper clips are used to hold abunch of papers together.
2. Paper clips are available in various shapes like as oblong shape, triangular, circular or elaborated shape.
3. Mostly, steel metal is used for manufacturing of paper clips, but some plastic paper clips are available in the market.
4. Some new modern paper clips include spring-fastened blinder clips and plastic coated paper clip which are multicoured.

Interpretation Introduction

(b)

Interpretation:

The methods used to manufacture I-beams used in bridges needs to be explained.

Concept Introduction:

• The I beam is also known as H-beam
• I-beams are mainly used in construction and civil engineereing.
• Generally, these are made up of structural steel. Also, composite material and concrete is used for manufacturing.
• In india, the designations given for the I-beam are as −
1. ISJB − Indian Standard Junior Beams
2. ISLWB − Indian standard Light-Weight Beams
3. ISLB- Indian Standard Wide Falange
• This desingations of the beam is followed by depth of section in mm.

Interpretation Introduction

(c)

Interpretation:

The methods used to manufacture copper tubing which connects to copper plumbing needs to be expliained.

Concept Introduction:

There are two types of the copper tubing available. They are Soft copper tubing and Rigid copper tubing.

The soft copper tubing −

Tubing is used to ease travelling around the obstacles present in the path of tubing. This is known as soft copper tubing.

It is mainly used in heat pumps and air conditioners (Split-system).

The Rigid copper tubing −

The popular choice for the water lines is the rigid copper tubing. This cooper became rigid because of the use of drawing process during the manufacting.

Interpretation Introduction

(d)

Interpretation:

The method used to manufacture steel tape in measuring tape needs to be explained.

Concept Introduction:

In general, a measuring tape is flexible ruler. It is used for distance measuring purpose. It is made up of plastic, fibre glass, ribbons of cloth or metal strip with linear marking measurements.

The design purpose for manufacturing of measuring tape −

1. A pocket sized tape to measure the long length.
2. Ease of measurement of distance or length around the critical curves or corners.
3. To withstand more tear and wear.

Interpretation Introduction

(e)

Interpretation:

Explain the method used to manufacture Head of Carpenter's hammer.

Concept Introduction:

• In early days, the hammer is made up of wood or ash.
• Now a days, for manufacturing of head of hammer, various best metals are getting used.
• The handle of the hammer is attached to the head through the eye of the head (hole).
• The head of the hammer should be tough in order to resist the deformation.
• Steel Head of the hammer is made with the proper hardening process.
