I thought the question about the 4 stroke cycle is confusing. Is the air sucked in or pushed in by atmospheric pressure? I think both are right!

Only 90%, me

Not trying till I beat everyone at the plane chucking

90%

I think it was the pully Q's that let me down. I never covered that at school.

I only got 82, but I'M being honest, and as we are all making excuses, mine is ' I just pressed any button in the end as I got bored'!!

Only 92%

On the one with multiple pulleys I worked out the correct answer then clicked the wrong option

. The other three I'm blaming on badly worded questions...

I got 80. Scraped through...

Is the air sucked in or pushed in by atmospheric pressure? I think both are right!

That one got me too - is the piston actually sucking or is it just the pressure difference that forces air to occupy the empty space?
(vacum abhoration and all that)
I went for the 'atmo' answer myself.

I went for sucking - if the engine simply opened the inlet valve and didn't pull the piston down, atmospheric pressure wouldn't push the air in, would it? You'd have roughly atmospheric pressure on both sides of the piston and nothing would happen.

'swot I said to - surely THAT was right?

Thats pretty cool ... 86%, I think it was the pulley lifting ratios that got me!

Sadly I went back and checked, it is in fact atmosheric pressure that charges the chamber.
