The post How Can We Use A Lever To Move An Object Without Picking It Up? first appeared on Learn Science, Robotics and Artificial Intelligence.]]> We encounter various types of lever in our everyday lives: opening a drink with a bottle opener, cutting paper with scissors, taking the lid off a paint pot using a screwdriver, and – the simplest of all – playing on a seesaw in the park. Yet, the principle of levers is sometimes so natural to us that we do not pay any attention to how it actually works.

ere are four basic elements to consider when using a lever:

  •     Pivot – the point around which something turns
  •     Beam – a wooden plank or solid rod that rests on the pivot
  •     Load – the item or object being moved or lifted on the beam
  •     Force – the effort or input needed to move the beam and the load

The post What Are The Different Kinds of Levers? first appeared on Learn Science, Robotics and Artificial Intelligence.]]> Levers  are a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort, the lever is divided into three types. Also, leverage is mechanical advantage gained in a system. It is one of the six simple machines identified by Renaissance scientists.

A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the mechanical advantage of the lever. As such, the lever is a mechanical advantage device, trading off force against movement. The formula for mechanical advantage of a lever is effort.

A simple machine is a mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force. Usually the term refers to the six classical simple machines that were defined by Renaissance scientists:

Lever
Wheel and axle
Pulley
Inclined plane
Wedge
Screw

From pre-historic times, man keeps finding ways that will help him simplify his life. As a cave man and a hunter, humans discovered fire and ways to ‘create’ fire. Fire helped him be safe from predators and improved the taste of food that he could now cook. As a nomad, man realized that rotating friction is less compared to sliding friction. A wheel was invented. 

Simple Machines are various tools and techniques that make human life easy. Pulleys, levers and hammer are examples of some simple machines. Most of the complex machines are composed of many simple machines put together. Can you think of how many simple machines are used in making a car or an airplane? 

Just to illustrate, if we look under the hood of a car, we will see – 

– fuel carburetor based on Bernoulli’s theorem

– steering wheel that helps rotate the steering rod

– gears to switch the available power between thrust and speed

– clutch plates using friction to transmit power

– brake shoes using friction to control the vehicle

– transmission mechanism using bevel gears to change the direction of rotation from that of the transmission rod to that of the wheels

– spark plugs (petrol engines) to convert heat to mechanical energy

& the list goes on and on!

 

Go to a manufacturing plant, research lab or an amusement park – we are always surrounded by a lot of equipment that are all made up of a large number of simple machines. 

Hollywood movies project that machines might overtake humans one day. With the advent of “intelligent machines” this might no more be just fiction. 

However, whatever the future may hold, it is fascinating to see how simple concepts that we study in our middle school shape up to make such complex systems.
