Author discovered value of free body diagrams.
- LordShredda 3y agoMaybe we can all learn the value of diagrams. Drawing on paper is not cheating!
- cheschire 3y agoThe article seemed like a common sense concept overthought, so I knew there just had to be a well trodden path that someone in the HN comments would bring up by name. Thanks for this!
- Tyr42 3y agoDo you know where I could find a free body diagram for a door with hinges? I don't understand why my doors are trying to close themselves. I think something is not level, but I don't understand the hinges though to draw a diagram myself.
- Zircom 3y agoGood discussion and an okay diagram in this thread https://engineering.stackexchange.com/questions/43338/how-do-you-calculate-the-shear-force-on-the-screws-that-connect-a-door-to-a-jamb https://engineering.stackexchange.com/questions/43338/how-do...
- rahkiin 3y agoThey auto-close when the top hinge is more to the outside then than the bottom hing, or the whole frame is tilted towards the inside (where the door does not swing into). You can try adjusting the hinges with a tool. In an ideal situation everything is level in all directions.
- gibspaulding 3y agoThis hurt my brain. I guess we envision inside and outside on different sides. Not sure if this is any clearer, but the door will close itself if the bottom hinge is offset from the top in the direction the door opens. Picture the angle of the bottom of the door when it is open 90 degrees and it might be easier to visualize why it falls shut.
- rahkiin 3y agoYes, we are saying the same :)
