Hills mechanism

Okay kiddo, imagine you have a toy car that you want to push up a ramp. The ramp is inclined and can be changed to be steeper or less steep. When you push your car up the ramp, it gets harder to push the higher it climbs.

Now, let's imagine that the ramp has two different heights at the opposite ends, kind of like a hump. This is called a hill's mechanism.

When you push your car up this kind of ramp, you'll notice that it's easier to push the car up one side of the ramp than the other even if the steepness is the same. This is because one side is taller, and this makes the toy's wheels roll down the opposite side faster because of gravity.

This means that the car rolls down the hill more easily because the taller side of the ramp makes the wheels move faster, which makes it easier for the car to move up the opposite side.

The Hill's mechanism is used in many engineering and industrial applications like escalators and conveyor belts to move objects from one end to the other with minimum effort.

So there you go, little one. That's a Hill's mechanism in simple terms.
