Imagine a small room, maybe 3ft x 3ft, with six fully grown adults packed inside like sardines. Now image you were somehow squeezed into that room. Do you think you would be able to move around freely? What's stopping you from dropping to the floor and doing 10 push-ups?

When a nail is driven into a block of wood it doesn't remove bits of sawdust like a screw does. In fact the wood that should have been removed to make way, is violently compressed and desperately trying to get back into its regular station of life - occupying the space said nail has now so churlishly taken.

This extreme pressure creates the friction needed to ensure the nail is a permanent addition to our block of wood.

The lifelong, unwavering pressure on our nail will never tire, never relent, keeping it firmly in place until elements and old age give way to rotted wood.

Now go hang a picture.

2 ways that friction can be used in a structure?

Friction is important for all sports. Without it it becomes really hard to accelerate For example a 100m sprinter. It would be great for him if there wasnt any air resistance (as long as he can breath). But he needs friction on the floor to push himself forward.

What keeps and inflated balloon from falling down if you rub it against your hair and place it against the wall?

When you rub a balloon against your hair, it becomes negatively charged due to the transfer of electrons. This negative charge creates an electrostatic force between the balloon and the wall, causing it to stick. The force between the negatively charged balloon and the neutrally charged wall is strong enough to counteract the force of gravity and keep the balloon from falling.
