4/24/2023 0 Comments Simple catapult![]() Now let’s get building and making pom poms or paper or cotton balls fly! You may need to try a few different placements of the load, fulcrum, and effort to make the highest-flying catapult possible. Placement: The center toilet paper roll fulcrum, the load, and effort placements all impact the mechanical advantage.Load: The amount of force needed to lift the pom pom or cotton ball.Effort: The amount of force you use when you press down on the catapult.How high your object flies depends upon a few things: The power in this catapult is dependent upon the mechanical advantage of the lever that you build. ![]() Mechanical advantage is a measure of how much the force you put into the machine is multiplied into an output force. So now you know what kinds of machines there are, why would you build one? Because machines make life easier! They create what’s called mechanical advantage. Screw: An inclined plane wrapped around a pole that can lift objects or hold them together.Wedge: Two inclined planes put together and helps push objects apart.Inclined plane: A hard, flat surface with one end higher than the other.Pulley: Adds a rope to a wheel which allows you to change direction of a force.Wheel and axle: A wheel with a rod attached to the middle that can help lift objects.Lever: A stiff board that rests on a center turning point called a fulcrum that is used to lift objects.Here are the six types of simple machines: A catapult uses the power-increasing simple machine called a lever. This project is a perfect opportunity to learn about simple machines, the building blocks of all things that move.
