@Ruslan That is true. The question is about the symbol used for derivatives, and that's what I meant.

comment Symbols of derivatives
@HDE226868 I don't believe so. This answer math.stackexchange.com/q/317338 gives the mathematical answer. But the conclusion is e.g. that $\delta$ is never used in math. I would like to know exactly what the symbols mean when used in physical equations.

comment Newtons third law and unbreakability
The table will exert a normal force to hold up the stuff on it. This hold-stuff-up force has a limit, which is when the table cannot withstand it and breaks. The the 1000 kg does not have to push with 1000 kg but just with what is enough for the table to break.

comment Torque for a door
@user117913 Clarifying picture is added. There is a torque caused by the weight. That is true. But that torque is not turning the door around the vertical axis as the question asks for. It is turning the door about a horizontal axis.

comment Torque for a door
It's not about the size of anything. It's about the direction. Look at a door in your home. Make sure what axis it is turning about. Then ask yourself, which way is the weight pulling. Is it pulling in a direction that will turn the door about that axis? Nope.
