Earnest There's no such thing as a stupid question on this forum--> oh yes my questions often are xD
do you mainly see the mean of transport inside firms or factories?
No is it a truck?
No regarding the position of the wheels: are them positioned under the mean of transport as in a car for instance?
Yes but it's not a car If not, are them like in a conveyor roller? I mean...are the wheels the main source for the mean of transport to move?
Yes (e.g. in an airplane, which is not our mean of transport, there are wheels, but its main source to fly are the wings...except of course the engine)
It's not an airplane, and we're probably left with the one mode of transport not guessed at this stage. Does the remove of the keg provoked something to suddenly stop?
No something to suddenly start?
Something moves relevantly.
