Concept of simple and compound machines
Texte du Storyboard
- Hello! Today we are going to talk about the concept of simple and compound machines and we re going to start eith simple machines
- Do know what is a simple machine? A simple machine is a machine that is used for transform a resistant force or lift a weight in more favorable conditions. They are in the form of mechanical work and all its parts are rigid solids.
- 🕹️
- They are only 6 types of simple machineslever: The lever is one of the most important is a rigid bar that can rotate around a fixed point, the fulcrum.pulley: .The pulley is used to raise heavy objects to a certain heightinclined plane: In the inclined plane the force of the weight breaks down into two components. Thus, the effort required to lift the load is less.Wedge: the wedge is made up of two somewhat sharp inclined planes, thus creating a lacerating contact point, which allows cutting or tearing solid objectsWheel: Thewheel is a circular device that is attached to a rigid bar at its center. A force applied to the wheel causes the axle to rotate, which can be used to expand the force.screw: The screw is a shaft that has a slanted groove along its surface.

- I hope you understand the concept of a simple machine, now I'm going to explain the concept of a compound machine
- Compound machines are those mechanical devices that have been formed from two or more simple machines that are connected / together.
- These are 3 examples of compound machines:wheelbarrow: The wheelbarrow has 2 simple machines that are a wheel and a lever.scissors: The scissor is a palanc and it has a wedge to.bicycle: The bicycle has many simple machines: levers on the brakes, the chainring and rear sprocket that make up the chain gear, and the wheels.
