Hello, My name is Bobbie, and today we are going to be identifying all the simple machines that pop up in my day to day life!
This here is a locker, A locker on a hinge can definitely be modeled as a lever. With the Fulcrum at the End Opposite the ForceYou open and close a locker (apply the force) at the end away from the hinges which is the fulcrum. The load moved is the locker door itself.
This elevator is an example of a pulley. Pulleys with large metal cables are used in modern elevators. The cable is wrapped around a groove in the wheel and axle. An electric motor pulls the cable, lifting the car between floors. Several pulleys can be combined to reduce the necessary work to lift a load.
A Day in The Life of Bobbie !
A wedge is really an inclined plane turned on its side. But instead of helping you move things to a higher level, a wedges helps you push and break things apart. The blades of a knife is an example of a wedge, because knifes use a sharp, inclined surface to cut through, foods,like cake!
Here is our first simple machine, a second class lever.
Our second example is this elevator, which is an example of a pully.
See! We use simple machines everyday, in our day to day life! The make a big impact on everything we do and make things easier. Science rules!
Our fifth example is this door. It is considered a Wheel and Axel
To open this door, you must use a door handle. A doorknob is considered a wheel and axle because it has a wheel portion, the knob, and an axle, the rod in the door, that turn on the same axis.
Our forth and final example of a simple machine is this.
