Static Door Hinge Problem

To solve this check that your door jamb is on the same plane so the door can close properly.

Static door hinge problem. Simply tap the pin back into the hinge and test the door. Works good now rjsurfer. The hinges are placed symmetrically at the door s edge. Hence our task is to find the forces from the hinges on the door.

The ideal is a 1 8 inch gap between the door and jamb at all points. I was also able to use a screw driver to open the jaws of the friction hinge a smidgen. If a door binds open it grasp the knob and lift up to see if a hinge is loose. Mine i had to adjust the camber as i couldn t get it to latch withough slamming.

In the initial analysis of a problem hinge joints should always be assumed to exert a force in an arbitrary direction and then you must solve for all components of a hinge force independently. When this happens your door will not close tightly for example the top corner sticks out away from the jamb. One of the most common problems that might affect your door installation process is caused by the hinge plates being out of alignment. Forces on door hinges a swinging door that weighs w 400 0 n w 400 0 n is supported by hinges a and b so that the door can swing about a vertical axis passing through the hinges figure 12 16.

The door has a width of b 1 00 m b 1 00 m and the door slab has a uniform mass density. If a door binds and a loose hinge is not the problem close it until it just touches the jamb don t force it closed and use a pencil to scribe a line where the door needs to be trimmed. Three forces act on the door slab. Using a hammer strike the pin in the middle this will cause a slight bend in the pin.

An unknown force. An unknown force. Mark both sides of the door. The fix apply some resistance in the hinges.

In this example the elbow force happens to be vertical because the problem assumes the tension by the biceps to be vertical as well. The forces that the door exerts on its hinges can be found by simply reversing the directions of the forces that the hinges exert on the door. Start by closing the door. This will keep the weight of the door from binding on the other hinges.

On the latch side a door is cut at a slight bevel to make it easier to close. Remove the top hinge pin and lay it on a concrete floor.
