You can try using a rubber band or a piece of Duct Tape to provide extra grip on the nubby screw head and then twist it counterclockwise to unscrew it. Alternatively, you can use a pair of pliers or a screw extractor tool specifically designed for removing stripped or damaged screws.
It may take less force to unscrew a screw because when you were screwing it in, you might have overtightened it or created more friction between the screw threads and the wood. This can make it easier to break the initial resistance and unscrew the screw compared to when you were driving it in.
If the blade on your pencil sharpener doesn't have a visible screw, it likely attaches using friction. Try gripping the blade firmly and twisting it counterclockwise to unscrew it from the sharpener. Be careful to avoid applying too much force in case the blade is secured differently.
The only difference is the base. Edison screw connectors have been known to work loose. Over time the heating and cooling can make the base unscrew and form a bad connection. A bayonet connector does not suffer this disadvantage and is quicker and easier to change.
The IMA (ideal mechanical advantage) of a screw is determined by the ratio of the circumference of the screw head to the pitch of the screw thread. The formula for calculating IMA is 2πr/p, where r is the radius of the screw head and p is the pitch of the screw thread.
The mechanical advantage of a screw can be found by dividing the circumference of the screw by the pitch of the screw. In this case, the total mechanical advantage is equal to the circumference of the simple machine to which the effort force is applied divided by the pitch of the screw.

To screw and unscrew things?
To unscrew a stripped screw, you can try using a rubber band, a screw extractor tool, or a rotary tool to grip the screw and turn it counterclockwise.

It may take less force to unscrew a screw because when you were screwing it in, you might have overtightened it or created more friction between the screw threads and the wood. This can make it easier to break the initial resistance and unscrew the screw compared to when you were driving it in.
The screw may be stuck and won't unscrew due to rust, debris, or overtightening. These factors can cause the threads to bind, making it difficult to turn the screw.
To unscrew a screw, you need to turn it counterclockwise using a screwdriver or a similar tool. Apply steady pressure while turning until the screw is fully removed from the surface.
there is a little screw on the throttel cord and you unscrew it all the way out . there is a little screw on the throttle cord and unscrew the screw all the way out.
To unscrew a stripped allen screw, you can try using a rubber band or a piece of steel wool between the screw and the allen wrench for better grip. You can also use a screw extractor tool or drill out the screw carefully.
To unscrew a broken screw, you can try using a screw extractor tool or drilling a small hole into the screw and using a screwdriver to remove it. Another option is to use a rubber band or super glue to grip the screw and turn it counterclockwise.
You can unscrew a screw without a screwdriver by using alternative tools like a coin, a butter knife, or pliers to turn the screw in the opposite direction until it comes loose.
