MECHANICAL ENGINEERING MODULE || ALL
ANSWERS ARE CORRECT 100%.
What does a mechanical engineer do? correct answers applies the principles of physics and
material science for analysis, design, manufacturing, and maintenance of mechanical systems
What does mechanical engineering involve? correct answers the production and transmission of
heat and mechanical power for design, production, and operation of machines and tools
examples of things mechanical engineers work on correct answers biomechanics, crawler
transport, robots, acoustics,
object of developing vehicle correct answers fastest, lightest, heaviest load
Gears correct answers cogged wheels fixed to shafts that mesh together resulting in power
transfer; used to change speed, torque, or direction
Pitch Circle correct answers At the effective diameter, D
N correct answers number of teeth
Speeds of gears vary correct answers Inversely, because:
V1 = 2πr1ω1 and V2 = 2πr2ω2
V1 = V2 because the gears are touching
so r1w1 = r2w2
Torque varies correct answers Directly
Gear Ratio correct answers ratio of the output gear diameter to the input gear diameter
(N out) / (N in)
Spur Gears correct answers simple, cheap
operate on parallel shafts
Helical gears correct answers -more efficient, better design, smoother
-develops end thrust which can be overcome by the use of thrust bearings
-used for higher velocity
BEVEL and MITER gears correct answers -used for right angle drives
-high efficiency
-MITER gears have 1:1 ratio
-application: rear differential
Differential correct answers -when both wheels can turn, they have the same velocity
