Survey of engineering material and processing equipment

Survey of engineering material and processing equipment

Part 1: Survey of Materials

A: We were given samples of some martials like wood plastics, different types of metals and rocks. Following were our observation

Look of materials:

Carbon Steel

Aluminum

Rock

Cast Iron

Steel

Wood

Touch, handle and feel of materials:

Wood was easy to handle and it was soft and light weight. Steel was hard and Aluminum was relatively soft to touch. cast iron was in the raw form and was harder than aluminum. Rock material was heavy weight and soft to touch.

Identification of materials:

We identify the following materials:

· Wood

· Cast iron

· Steel

· Aluminum

· Rock

Comparison of application of these materials:

Wood: Wood is used for making furniture and stairs and doors. It is also used as fuel.

Cast iron: It is used in number of applications in daily life like holding fluids in pipes, pans, pots and other domestic useable things. It is also used in industries at large scale for machines and tools.

Steel: it is used in manufacturing of heavy machinery, construction of roads and bridges and also has number of application in daily life.

Rock: it is used for making cement, building material and cosmetics and it is also being used in new technologies.

Aluminum: it is used in manufacturing of pipes, stairs, windows, vehicles parts.

Processing of materials:

Wood:

Cast iron and steel:

Aluminum:

Rock:

B: Research of materials in group:

· Abundance, availability and cost of materials:

Material	Abundance	Availability	Cost
wood	more abundant	Easily available	cheap
Cast iron	More abundant	Easily available	Less expensive
Steel	Less abundant	Easily available	Less expensive
Aluminum	Less abundant	Easily available	expensive
Rock	Less abundant	Less available	expensive

· Structural makeup:
