The force needed to turn a door knob depends on factors such as the condition of the knob, the type of mechanism it has, and the resistance from the latch and hinges. On average, a person might exert between 10-15 pounds of force to turn a typical door knob.
Yes, a door knob can be considered a type of lever. When you turn a door knob, you are applying a force at one end of the lever to create a mechanical advantage in opening or closing the door.
A door knob acts as a lever because it allows you to apply a small input force to create a larger output force to turn the latch and open the door. The knob is positioned away from the hinge point, allowing for leverage to be exerted on the door mechanism.
A circular doorknob is a force magnifier because it allows you to apply a greater force to the door than if you were pushing it directly with your hand. The circular shape of the knob helps to distribute the force more evenly, making it easier to turn the knob and open the door.
No, a door knob does not typically use a wedge. A door knob functions by allowing a person to grip and turn it to open or close a door.
Torque= length x force. Lenght is the distance to an object. Force must be perpendicularly acting on the object. In your question, you did not specify neither force and length of the knob. So I cannot give you a torque value. I believe the SI unit for torque is "Nm", assuming that you calculated your torque using all SI units. Then you have to convert Nm to pounds.

Turn that knob to activate the pressure.The knob on the door was stuck solid.

To open a door knob with a hole in it, you can use a small tool like a paperclip or a screwdriver to push into the hole and turn the knob. Insert the tool into the hole and apply pressure while turning it in the direction that unlocks the door. Be careful not to force it too hard to avoid damaging the lock.
The knob may break.
The wheel of a doorknob multiplies force through the principle of leverage. When you turn the wheel of a doorknob, the rotation creates a mechanical advantage that allows you to apply a smaller force over a longer distance to open the door. This leverage magnifies the force you apply, making it easier to turn the knob and open the door.
