MECHANICAL ENGINEERING TEST 1
QUESTIONS AND VERIFIED
ANSWERS|100% CORRECT|GRADE A+
Tools in Box - ANSWER hammer, phillips screwdriver, flathead screwdriver, crescent wrench, hex keys,
digital micrometer, tape measure, utility knife or boxcutters, drill
tools in the lab - ANSWER clamps, drill bits, miter saw, sanding block
optimization - ANSWER improving on existing designs, it is rare for engineers to create something new,
try to make things better, lighter, stronger, cheaper, etc.
tinkering vs. engineering - ANSWER tinkers just start building, more trial and erro, no planning, way to
gain experience
engineering: do calculations first, use experience
engineering design process - ANSWER 1. define the problem
2. do background research
3. specify requirements
4. brainstorm
5. develop solution
6. test solution
7. improve solution
miter saw - ANSWER used to make cuts at an angle, always secure the turn base by turning the grip 90
degrees counter clockwise to lock position
paddle bit - ANSWER available in diameters from 6 to 36 mm. used for rough boring in wood. They tend
to cause splintering when they emerge from the workpiece. Woodworkers avoid splintering by finishing
the hole from the opposite side of the work. Spade bits are flat, with a centering point and two cutters.
