this is how you do it because we are on a lever. A lever is a simple machine consisting of two parts:A rigid arm or barA fulcrum which is the point on which the rigid are or bar rests and on which it pivots.for example since the fulcrum is in the middle , when you push on the push on one side of the seesaw (the input)the person goes down , but makes the other person on the other side of the seesaw go up.
OH okay
okay lets go somewhere else.
oh thats easy
what do we do with this
A pulley is a wheel and axle with a groove around the outside where a rope, chain, or belt is connected. An example of a pulley is the device used to raise a flag to the top of a flag pole. A pulley works by reversing the direction of your lifting force.
oh that makes sense
wait how will we open the door.
this I was able to open the door thanks to wheel and axle. A wheel and axle consists of two circular objects of different size. The axle is a rod that goes through the wheel which allows the wheel to turn. this doorknob is an example of a wheel and axle.
Omg today I learned so much about simple machines
