Like a Machine
By C.J. Fernandes 3-4🇺🇸
What is a simple machine?
A simple machine makes doing something easier but still having the same amount of work. By exerting an input force less than what you would normally need to lift the load. With the pulley ,the rope is the distance which decreases the input force out to make it easier. Inclined planes just increase the distance to decrease the effort used.
At Timbercreek Elementary there was an inline plane by the stairs to help carry a wheel chair or luggage easier by just rolling it up instead of lifting it up to increase distance and decrease effort.
This is a wedge in the band hall. It is used as a door stop because you put little input force and the wedge creates output force to change the direction of the force between the floor and door to stop it.
The pulley was located at Timbercreek Elemtary and the pulley itself is at the top raises the flag. By pulling the rope it moves on the pulley which creates less effort for you. But the more rope , the less effort force but takes more time. A pulley is a rope over a grooved wheel.
This screw holds up my light switch. A screw is a inclined plan that is wrapped in metal so when you twist it with an input force the screw holds the light up. The more metal wrapping the more distance it covers. A lever is a rigid bar that moves around fixed points.
