PROJECT MATERIALS SELECTION

Group 19 NJT2C

PRODUCT ANALYSIS - What is the function of your product? - How do the components interact? - How is it made? - What should it cost? - What should it look like?

What is the function of your product? -using with 6 sockets

-can slide in and slide out-have switch-safety with fuse- a universal electrical outlet-installation with table- power less than 2000 W

HOW DO THE COMPONENTS INTERACT?

1.Puller 2.Outer tube 3.Switch and sockets 4.Holding plate 5.Hole

6. Pin7.Outer tube8. Fuse

How is it made?

What should it cost? -Less than 200 Bath

What should it look like?

- modern- meet the design specifications- It actually works

MATERIAL SELECTIONo - What are the performance requirements?o - Based on the material selection chart, what

materials can you use?o - What are their mechanical, electrical, and

thermal properties?o - How much do they cost?o - Can they be recycled?

WHAT ARE THE PERFORMANCE REQUIREMENTS?

Requirement properties

Must conduct electricity Electrical conductivity

Light and stiff Low density and high strenght

Cheap Cost per kg

Non oxidation Non-ferrous materials

BASED ON THE MATERIAL SELECTION CHART, WHAT MATERIALS CAN YOU USE?

Young` s Modulus - Density

Strength -Density

Streng - Toughness

Strength – Max.Service Temperature

Resistivity -Cost

WHAT ARE THEIR MECHANICAL, ELECTRICAL, AND THERMAL PROPERTIES?

Mechanical Properties
