Physics Puzzle for the Gearheads

[BrianSoddingBoru4]

something else turns on when it reaches that temp

Nope.


I guess nobody else here has a 2 post lift - or has worked on them. (Not the case on the automotive forum I frequent.)

So - I guess a hint is in order.

...
I can tell when it's 70°f when the lift is moving upwards by the sound.

Got it! There's a microchip/speaker combo in the lift that's temperature activate and says, 'It's 70 degrees! It's 70 degrees!'

What do I win?
