● What important milestones have occurred during the progression of the engineering field?.
Answer: Henry Fords assembly line Wright brothers first flight Thomas Edison's light bulb
Robert Goddars' liquid fuel rockets
● What are the important principles of the problem solving process?. Answer: identification of
a need, problem definition, researching, constraint, criteria, alternative solutions, analysis
● What are the steps in the design process?. Answer: Identify the need, research and
gathering info, develop solution (alternative solutions), choose a solution (analysis), construct
a prototype, test and evaluate
● How to analyze solution/ identifying strengths and weaknesses?. Answer: Efficiency Cost
Safety Functionality Availability of materials Durability
● How to develop details of a solution?. Answer: Scale model Inventor (dynamic simulation)
Orthographic Isometric drawing Techno CNC + 3D printing
● How to develop, test, and redesign prototypes?. Answer: Test for safety and durability Test
for efficiency
● How to explain components of set up, machining, casting, molding, welding, and finishing?.
Answer: Turning- lathe Milling- makes square objects Casting- turns liquid into mold Welding-
arc, spot, gas (oxyacetylene) Undercutting- welding reduce cross sectional strength Finishing-
, painting
● How to identify and use common hand tools. Answer: Straight edge- ruler VIC (vernier
caliper)- measures inside/outside distanxes
● How to identify and properly use fasteners?. Answer: Machine srews- hex nuts Wood
screws- course thread/pointy Sheet metal- pointed heads, sharp fine threads Thread
Rotation= UNC 1/4(diameter)-20(thread per inch)-2(thread length)-2A(type of thread)
● How to estimate and measure the size of objects using SI and US units?. Answer: 1 inch =
2.54 cm 100 ft = 28.3 L 1 gal water = 7-8 lbs
● How to explain the role and quality control in manufacturing?. Answer: -Controls the quality
-bSigma- stands for manufacturing for standardization -International organizations
-Manufacturing tolerance
● How to measure with percussion to olds and instruments?. Answer: 7.00 sleeve(0.5) 0.25
thimble
● What role does quality control plays in assembly and fabrication?. Answer: -Improves
quality and reputation -Reducing execution time -Lower costs
● What are the roles of supplying and outsourcing?. Answer: -Reordering levels are set -No
over stocking (to attain materials in time w/o overstocking)
● What does the order and methodology of the assembly process consist of?. Answer:
Operations Storage Transportation/Delays Inspection
● What are the attributes of common materials?. Answer: Ferrous- high weight/ lower
conductivity/ easily corrodible/ magnetic Non Ferrous- malleable/ high conductivity
● How to make an oral presentation?. Answer: Practice Don't read from slides Speak to the
audience
● How to interpret aspects and/or types of engineering drawings and plans?. Answer:
Orthographic drawings Dimensions/ line drawings
● How to express data in tables, graphs, and charts?. Answer: Bar graph- qualitative
Histogram- Quantitative
● How to contribute to a team project?. Answer: Communication Common goal, vision Find a
good team
