STEM Model Wooden Lever System

Activity Kit for Kids

Give me a place to stand, and I will move the world, said Archimedes 2000 years ago. The Greek mathematician, scientist, and inventor were discussing the principle of the lever.

With this model, you may not be able to move the Earth but you can surely understand the underlying ratios of force, load, and distance using this simple machine.

Construction DIY Based Activity Kit

Here It Is:
  • Specially designed
  • Premium Quality
  • Perfect Gift

The Greek mathematician, scientist, and inventor were discussing the principle of the lever. With this model, you may not be able to move the Earth but you can surely understand the underlying ratios of force, load, and distance using this simple machine.

WHAT TO DO?

1. Place a unit weight at 5cm mark. 2. Now balance this weight by placing a different weight on the other side. 3. To balance weights of different amounts on both sides, how should we place them? Should the heavier load be closer to the fulcrum or the lighter load? How much? Explore all this using the model. WHAT’S GOING ON? 1. A lever amplifies an input force to provide a greater output force. 2. The ratio of the output force to the input force is called the mechanical advantage of the lever. 3. The effort arm is equal to the distance from the fulcrum to the point of applied effort, and the load arm is equal to the distance from the fulcrum to the load weight (which is to be lifted). 4. Effort (force applied by you) multiplied by the length of the effort arm is equal to the load multiplied by the length of the load arm. 5. This means that the longer the effort end, the less the force required to raise the load. 6. Therefore, if you are trying to lift a particularly heavy stone, it is best to use a longer stick. EXPLORE 1. If two children are playing on a seesaw, and their weights are different, should the heavier child sit near the fulcrum or away from it, to balance the seesaw? 2. Take a pipe and hang a bag on it. Now lift the bag by holding the pipe close to the bag. Guess the weight of the bag. Now try lifting the same bag by gradually moving the hand away from the bag. Does the bag feel heavier? Why? The weight of the bag has surely not changed. So why do you need to apply a larger force to lift the same bag?

Film Projector Do-It-Yourself Working Model- KIT (Film Projector Do-It-Yourself Working Model- KIT)

Product description

A Film Projector Is A Mechanical Device Used For Showing Motion Pictures. A Movie Projector Is A Device That Continuously Moves Film Along A Path So That Each Frame Of The Film Is Stopped For A Fraction Of A Second In Front Of A Light Source. The Light Source Provides Extremely Bright Illumination That Casts The Image On The Film Through A Lens Onto A Screen. HOW IT WORKS There are four basic parts that make up the average movie projector. They include the spooling system, the lamp, the lens and the audio system. While each of these systems consists of multiple parts and processes, almost any motion picture can be shown using only these four systems. Once a band of film is placed on the spool of the film projector, the spool is turned using an electric motor. As the spool turns, it transfers the image. the image is centered in front of a bright lamp, which projects light through the image and transfers it to the screen. Before the image leaves the projector, it passes through a lens, which magnifies the image to multiple times its original size. Product Specification The framework is made of Medium Density Fibre (MDF). The parts get cut by a Laser machine. Assemble the parts using Interlocking system i.e. one has to engage its parts with each other by overlapping or by the fitting together of projections and recesses. Please be gentle, careful while assembling. This product is designed for a single use. Product Specification The framework is made of Medium Density Fibre (MDF). The parts get cut by a Laser machine.
