Door knobs that are loose aren't just annoying, they can compromise your building's security, making it crucial to solve the issue quickly. Fortunately, a doorknob that is loose or handle is fairly simple to repair. Depending on the type of lock you have installed on your door, there are several ways to fix this. Some lock systems have visible mounting screws that are easy to access, while others have a backplate that hides the screws that hold it together. If your door is the one that is hidden, the process may be more complicated.
The majority of interior doorknobs are designed to slide over a spindle that is cylindrical, which is mounted in the door as part of the latch assembly. If the knob you have is jiggly it could be due to a small screw, called a set screw, located on the inside of the doorknob which is keeping it from sliding over the spindle. You can utilize an flashlight to locate the set screw, then tighten it using an Allen wrench. Once the screw is tightened by turning the knob, check if it feels solid.

Depress the button with an screwdriver with a flat head, and then slide the knob across the spindle. The knob should click into position as you do this, signalling that it is in the correct position on the spindle.

In this situation an easy fix would be to spray the lock with graphite spray or lubricant made of silicone to coat the pins and allow them move again.
If the problem is more serious and the key is bent it may be necessary to have it straightened by an expert. A professional locksmith can use a special tool to straighten the key that is designed with an angled end that fits into the groove that is recessed on the tip of the key. This kind of tool can't be found in hardware stores. However you can purchase a kit that includes the required tools online or from a locksmith.
A soiled or dirty lock is a different possibility. Dust can accumulate over time in the lock's cylinder and causes the springs or pins to get stuck. In this case, spray the lock with WD-40 or graphite spray to clean out the pins and restore them to their original places.
If the key itself has become damaged, it could be a problem. Over time, repeated use may wear out the grooves of a key. This can lead to the key not fitting properly into the cylinder, so it's crucial to pay attention and regularly check whether your key fits properly.
In colder weather locks can freeze which can stop the springs and pins from moving when the key is placed. This can be a frustrating problem, but it is usually relatively simple to fix by heating the lock with hot water and then using an oil-based lubricant to re-lubricate it. If the lock is damaged or frozen beyond repair, it's likely to need to be replaced by an expert.

4. The Cylinder is Rotating
When a cylinder is rotated within a confinement gap it can cause hairpin vortices to form that can result in significant forces on the cylinder. These forces are proportional the radius of curvature that is dimensionless x and the confinement factor k. The simplified model that is presented here will predict the effect of these parameters on the torque and force on an encircled rotating cylinder. The cylinder's head, tube and main body are all composed of aluminum alloy.
