The doors are having hinges to support them. This hinge is too a type of bearing or is a Device which is using the effect like bearing to support. So, if you are opening the door, then the force you apply is greater if you open it from the part closer to the hinges.

There are some of the applications of the two force and three force members in the journal bearings. The difference between the two and the three force members is:
The basic type of motion of a body is not the translation motion only.
We first make equilibrium equations of the sections involving the journal bearings by considering all the three dimensional forces acting on the section chosen and then the free body diagram is made and solved.
