QUESTIONS AND ANSWERS GUARANTEE A+
✔✔What are the attributes of common materials? - ✔✔Ferrous- high weight/ lower
conductivity/ easily corrodible/ magnetic
Non Ferrous- malleable/ high conductivity
✔✔How to make an oral presentation? - ✔✔Practice
Don't read from slides
Speak to the audience
✔✔How to interpret aspects and/or types of engineering drawings and plans? -
✔✔Orthographic drawings
Dimensions/ line drawings
✔✔How to express data in tables, graphs, and charts? - ✔✔Bar graph- qualitative
Histogram- Quantitative
✔✔How to contribute to a team project? - ✔✔Communication
Common goal, vision
Find a good team
✔✔How to follow appropriate personal safety procedures? - ✔✔Need to know and learn
safety rules
✔✔What role of OSHA is in the technical workplace? - ✔✔Occupational safety + help
admin
Ensure safety standards are followed through
✔✔How to use appropriate safety equipment? - ✔✔Eye and ear protection
Safety shoes
Masks
Hazardous material storage
✔✔How electrical safety decries function? - ✔✔Circuit breaker-
to switch circuit off, surge protector, when it gets excess/ it converse excess to ground
✔✔How to solve problems using vectoring to persist forces? - ✔✔X Y components
Hypotenuse components
✔✔How to calculate and describe the effect of resistance? - ✔✔V=IR^2
W=VI
✔✔How to apply Ohms law, Watts law, and Kirchoffs law? - ✔✔Ohms law- V=IR^2
, Watt- power= voltage x current
Kirchoffs- sum of voltage in = sum of voltage out
✔✔How does AC and DC systems work and differ? - ✔✔DC current- flows in the same
direction
AC current- constantly flows
✔✔How to identify what causes resistance in a fluid system? - ✔✔Smoother pige inside
As few curves as possible motor cylinder piston
✔✔How hydraulic and pneumatic systems work? - ✔✔Pump, Valce, Motor/Cylinder
Hydraulic motor- generates power
Pneumatic- pressurized fluId
✔✔Three ways heat is transferred - ✔✔Convection- hot to cold (no direct contact)
Radiation- to contact (vacuum)
Conduction
✔✔How to convert between Celsius and Ferenheit? - ✔✔(X9/5)+32 <from C to F>
(-32X5)/9 <from F to C>
✔✔How heat conductors and insulators work? - ✔✔Head conductors relies on density
(more particles) heat can jump
✔✔How to solve thermal problems using appropriate units? - ✔✔BTU- British thermal
unit
1 pound of water needed to get 1 degrees F
✔✔What are the six simple machines? - ✔✔Pulley
Lever
Wheel and Axel
Wedge
Screw
Plane
✔✔How to solve problems using appropriate units in engineering systems? -
✔✔Increase velocity of liquid
Increase force or increase area absolute p + gauge = atmospheric pressure
✔✔How to identify the uses and types if inductors and capacitors? - ✔✔Capacitor-
stores electrical energy
Inductors- stores energy (w/ magnetic field)
✔✔How to use insulation to minimize heat flow? - ✔✔1. sealed windows (vacuum)
2. Fiberglass
