Mechanical Quiz! Attempt only if you are a qualified Mechanical Engineer!

[650lb Sumo]

These mechanisms have paired names, ie X and Y. Can you name them? (Two marks for each)

(1)

(2)

(3)

(4)

(5)

Can you name the item from its description or picture?

(6) Mixes fuel and air, to send the mixture into the engine cylinders
(7) Stores energy in the form of rotational momentum in an engine and dispenses it as necessary, smoothing the output
(8) The spiky things

(9)

(10) When a belt is twisted like this

Spoiler

(1) Ratchet and Pawl (the pawl is green) (For the first five questions: If you know one, but don't know which one it is you get ½. If you know one, and which one it is you get a mark. If you know both, but don't know which is which you get 1½.)
(2) Block and Tackle (the blocks are the pulleys)
(3) Mortar and Pestle (the pestle is the 'male' part)
(4) Rack and Pinion
(5) Cam and Follower

(6) Carburettor
(7) Flywheel. Automatic vehicles don't usually have them.
(8) Sprockets (cogwheels that engage with chains or similar)
(9) Gears (cogwheels that engage with cogwheels)
(10) Möbius Strip - used in (some) machine belts so they wear on both 'sides'

The pass mark is 8/15! How did you do?

I'm no ME expert! But I only got 4 right

 

[Tone C]

Normally I enjoy your quizzes.....


7 scored for me .

 

[ChickenBrother]

6/15

Not a ME but took STEM and some engineering courses. Got 3(both), 5a, 6, 8 and 9. Should have gotten rack and pinion but brain farted on that one.

Do you want to see some terrible looking ways oil?

12/15. I'm no ME, but I stayed at a Holiday Inn last night.

 

[William Huggins]

Extra points for knowing who invented some of them.....

 

[Your Salad]

I did surprisingly well for a retired chef. I'm no mechanical engineer but I did work at a sprocket and gear plant and did a stint as an automotive machinist.

Same. I forgot the pawl and I was literally standing in front of my bike.

 

[PaddyO'malley]

Mi got 8pts ngl tho mi got lucky on mobius strip ting mi went weh down di wiki rabbit hole affi mi look up Rick n Morty den mi rmmbr slowmobius di yute who be slowin' down tayum at di 1 party den me come across mobius strip ting was like 2 months ago but me neva forget ppl seh show nah make u smarter but it do still mi shoulda known di flywheel ting tho mi faddah taught me how fi hold di flashlight ting was emotionally charged shoulda activate di neuron ting iykyk

 

[Wilmer Digreux]

Lol i got 2

 

[Otto!]

How many of these do you need to build a sex robot? Asking for a friend.

Just a sprocket a vacuum pump lol

14/15.
Missed mobius strip I've never even heard of that shit. Flat belts haven't been used in serious industrial applications for a long ass time tho

I am a mechanical engineer also

Rove to advantage... Boom!

I whiffed #2, but tbf, we have riggers in the shipyard that handle that stuff.

I called #5 cam and "lifter", still gonna claim it.

Said "teeth" on #8. Never knew there was a functional difference between a sprocket and a gear.

I've heard of a mobius strip, but never heard anyone refer to a twisted drive belt as such.

7/10 for me. Oh well. I guess that's what BSME will get ya'.
