test Flashcards
key purpose of technical drawing
1.legal instrument
-communicate all the needed info to the people who expend resources; idea → reality
2.Legal purpose
-Instruction from engineer to the manufacturer
3.Standardisation (ASME Y14.5 & Y14.5M) aids in internationalisation; share -common language of engineering drawing
4.Documentation
-legal and tech for future modification
5.Problem solving & analysis
-Identify design flaws before production
-aids in simulation, stress and performance
ergo in workplace
1.Physical work env
-Thermal comfort
-noise and vibration
-proper lighting
2.chemical environment
- pollution
- ventilation
3.work physiology
- control excessive load
- avoid muscular fatigue
- enough rest pause
4.Body sizes
- fit body sizes of user
-adequate work size
- avoid overcrowding
5. safety and ergo
- performance feed back
-good housekeeping
SDOs in engineering
safety - prevent accidents (ASME)
standardisation - uniform guidelines (ISO)
technology - guide the development of emerged technology (IEEE)
environment sustainability - guidelines to decrease carbon; eco-friendly (ISO 14001)
support global trade and market access - refine technology trade barriers (IEC)
importance of standard
ensure safety (ASME BPVC)
maintain quality in materials (ISO 9001)
reduce cost (ASTM material testing standard)
technology advancement - sustainability & eco-friendly (ISO 14001)
support global trade (IEC)
