### Is weight distribution influenced by the location of the weight's attachment points (see drawing)?

Lets look at the equations Static equilibrium to obtain the unknows forces $~F_1~,F_2~$ you take the sum of the forces $~\sum F_i=0~$ and the sum of the torques about point A $~\sum_A\tau_i=0~$. you ...

### Where do these forces come from?

The one-word answer is torque. The door is not moving. That means that all forces must balance. So far so good. That is where the vertical forces on the hinges come from. The door has weight, which is ...

### Does the earth exert centrifugal force on us in air?

As pointed out in the comments under your question, whether or not you need to take account of centrifugal force (and/or Coriolis force) depends solely on whether you are using co-ordinates relative ...

### Is weight distribution influenced by the location of the weight's attachment points (see drawing)?

The line of action of the force of gravity on the 100 kg weight in the first diagram acts through the same point on the structure as the physical connection of the vertical support of the weight in ...
