Answer:
15.78 m
Explanation:
Length = resistance×area/resistivity
Resistance = 15 ohms
Area = πd^2/4 = 3.142×(0.15/1000)^2/4 = 1.767375×10^-8 m^2
Resistivity = 1.68 ohm-meter
Length = 15×1.767375×10^-8/1.68×10^-8 = 15.78 m
Answer Explanation : The general principles for design for assembly (DFA) are,
- MINIMIZE NUMBER OF COMPONENT
- USE STANDARD COMMERCIALLY AVAILABLE COMPONENTS
- USE COMMON PARTS ACROSS PRODUCT LINES
- DESIGN FOR EASE OF PART FABRICATION
- DESIGN PARTS WITH TOLERANCE THAT ARE WITHIN PROCESS CAPABILITY
- MINIMIZE USE OF FLEXIBLE COMPONENT
- DESIGN FOR EASE OF ASSEMBLY
- USE MODULAR DESIGN
- REDUCE ADJUSTMENT REQUIRED
STEPS TO MINIMIZE THE NUMBER OF PARTS
- USE OF INCORPORATE HINGS
- USE OF INTEGRAL SPRINGS
- USE OF SNAP FITS
- USE OF GUIDES BEARINGS
- USE OF COVERS
The engineering design process is a common series of steps that engineers use in creating functional products and processes.
Steps of the Engineering Design Process
Define the Problem. The engineering design process starts when you ask the following questions about problems that you observe: ...
Do Background Research. ...
Specify Requirements. ...
Brainstorm Solutions. ...
Choose the Best Solution. ...
Develop the Solution. ...
Build a Prototype. ...
Test and Redesign.
Process Engineer responsibilities include:
Developing, configuring and optimizing industrial processes from inception through to start up and certification. Assessing processes, taking measurements and interpreting data. Designing, running, testing and upgrading systems and processes.
