Bridge and tunnels main purpose is to be a medium of faster transportation, that's it, other functions are secondary.
Build a bridge? Sure depends in the place.
Drill a tunnel? Sure depends on what you want.
Heck, there are many forms to transport an object to another, I'm thinking teleportation in the future ;)
Multiple blocks and multiple chains can be infinite.
Start with one hair, one string, one block.
Add another.
Repeat.
That's it, it will be a fabric of blockchain.
...but
That's only a surface interweaving, why not add above or below the fabric?
A three dimensional blockchain. Strongest so far.
...then spice up with time
Links will decay and grow as time progress. That means a security feature that is living, breathing entity. Pure genius.
:Simple machines are static tools used as a medium of transfer of energy just as a glass as a container of water.
So what are the examples of simple machines?
Before we get into that the principle on a how simple machine works is based on engineering mechanics.
There are only two things to keep in mind. Force. Length. That's it.
What about time? or torque? energy? Nonsense.
Time is a rate, a measure of change, of movement, of one body in a point in dimension to the next.
Torque, on the other hand, is a mixture of force and length. They also call it moment, as in movement in respect to a neutral point.
Energy is what is transferred on the force. Force is the utility of energy. Distance is the measure of a physical gap between two points.
So let's head on to the examples.
Q. LEVER - a down force, fulcrum, object to move
W. WEDGE - a straight force cut
E. PULLEY - pull
R. WHEEL AND AXLE - pull and roll
T. SCREW - downward spiral rotation
Y. INCLINED PLANE - friction force
