The story is that I was describing an action happens in the car park in class, and I got stuck, I said something like: "after putting a coin in the slot of the parking meter, then the lever would be elevated automatically." I still don't know which verb should I use; I've got a couple of candidates - raise, lift, elevate. Which verb could be the best one? Or none of them is correct hh??
"Elevated" or "raised"
After you put a coin in the slot, the barrier would be elevated automatically.
After you put a coin in the slot, the barrier would be raised automatically.
Technically the device can indeed be considered a lever, since there is a pivot inside the machine and a mechanism that moves part of the bar a small distance so that the long part of the bar moves a long distance. However most people would call it a barrier rather than a lever, because - from their point of view as end-users - the role of the pole is to bar entry to the car park, rather than to help them move something.
