Why is it easier to pull out a nail but not a screw from wood?
The thread pattern of the screw anchors it in the wood. You not only have to pull against frictio, but also against the natural strength of the fibre and wood itself.
How can you tell if its a wood screw?
A wood screw will have a courser type thread and will have a sharper point.
Function of a screw?
to screw to pieces of wood together>.<
Why is it easier to insert a screw into wood than to insert a nail?
A screw holds wood together better than a nail because the threading of a screw provides a horizontal grip on the wood. Nails are driven down into wood and have nothing but the pressure of the wood to keep them attached, which means it is easier to pull a nail straight out of a board than a screw.

What is shear strength?
Shear strength is the ability of a material to withstand shear stress before it deforms or fractures. It is a measure of the material's ability to resist forces that cause parts of it to slide past each other in opposite directions. Shear strength is an important property in various engineering applications, such as construction, geotechnical engineering, and material science.

What kind of screw can you put in a tree?
Since tree trunks are made of wood, you can put a wood screw into them if you wish. It is always easier to screw in a screw if you drill a guide hole first.
What is the force that holds a nail or screw in wood?
Friction is the force that holds a nail or screw in wood. When a nail or screw is driven into wood, the friction between the fastener and the wood fibers creates resistance, preventing it from easily being pulled out.

Can you hammer a screw?
It is not a good practice, but people do it. Some will tap a screw with a hammer to start a hole. Others will drive it all the way in. That is bad for the screw and the wood.Hammering a screw is counter-productive and will not have good results:When you hammer a nail into wood, the sides of the nail compress the wood. The compressed wood wants to expand pressing on the sides of the nail. The pressure keeps the nail in place preventing it from coming out of the wood.When you hammer a screw into wood, the threads of the screw "chew out" the wood pressing it downward, possibly compressing it in a downward direction, leaving little or no wood to hold the screw in place The compressed wood, wanting to expand may tend to expand upwards pushing the screw out.
