Simple Machine: Definition, Types with Funny Home Examples

Hello friend !! This is your host and dost Abhishek, welcoming you to Engineers Rail‘s another blog post named- Simple Machine.

If you are keen to know the definition, and types including some common examples of simple machines, then you landed in the right place and this may be your final stop if you stay with me and scroll gently.

So, Without wasting much of your time, I am heading you towards the mainstream of today’s topic.

Definition of Simple Machine-

An object with the ability to change the direction of force or transform motion into another type of motion is known as a simple Machine.

These simple machines are known to increase the initially applied force and make things or work easy to do.

And there are basically six types of simple machines, that are-

  • Inclined Plane
  • Lever
  • Wedge
  • Wheel and Axle
  • Pulley
  • Screw

Mentioning, these types will be discussed down the road.

Type of Simple Machine-

There are six types of simple machines and they are-

  1. Inclined Plane
  2. Lever
  3. Wedge
  4. Wheel and Axle
  5. Pulley
  6. Screw

1. Inclined Plane-

As the name indicates, A surface which is tilted itself on its axis or tilted surface is placed on the plane surface with a higher angle than another known to be an inclined plane. The other name for the inclined plane is Ramp.

The pulling force of gravity pulled the object placed on the origin of the inclined plane with the help of an Unbalanced force which further helps in raising or lowering the object.

A common rule of thumb for sliding things on an inclined surface is that the greater the angle of tilt, the better and faster the sliding will be.

2. Lever-

A lever is a type of simple machine which has a function to change the direction of force upside down through a balance point, known to be a Lever.

A lever can consist of beam pivots on a balance point, called ”fulcrum” where initial downward force is applied on one end of the beam and due to a change in direction of force, Another end of the beam is lifted into an upward direction.

Types of Lever-

Lever consist of three types and they are-

  1. First Class Lever 
  2. Second Class Lever
  3. Third Class Lever 
I. First Class Lever-

First-class levers are those in which Initial force is applied on one end of the beam and load placed on the other end of the beam having a fulcrum in the middle.

This figure will clarify, have a look…First class Lever diagram

II. Second Class Lever-

Second-class levers are those which Initial force applied on the one end of the beam and load placed on the middle and having a fulcrum in the other end of the beam.

This figure will clarify your doubt, have a look…

III. Third Class Lever-

Third-class levers are those which Initial force applied in the middle of the beam and load placed on the other end having a fulcrum at another end of the beam.

Have a look at this image…

 3. Wedge-

Wedge is a triangular-shaped type of simple machine including two inclined planes forming a sharp edge at the end and a thicker shape on the other end.

Initial force is applied on the vertical edge of the wedge and this wedge can change postions according to your need, Unlike an inclined plane.

You can see many real-life events which are done through wedges including cutting a portion of the object, and lifting heavy loads, to hold the object from moving.

A wedge can be made up of metal, wood, stone or plastic.

 4. Wheel and Axle-

An object which is round in shape moves circularly with external force application, called Wheel. A wheel is not a simple machine alone without including an axle.

Suppose you have a box containing a really heavy load which won’t be pushed by you by any means due to resisting force applied on the ground called friction.

Here is the simple solution for your problem- Apply wheels under the load and it will move your heavy loads in a minute without putting too much effort into it.

A kind of shaft which helps to spin the wheel or pair of wheels, known as an Axle.

As you know, Axle will not count as a simple machine without including a wheel and due to the addition of both wheel and axle, friction is greatly reduced.

As the effort is applied to the axle, Axle starts to roll and with that wheel also starts to spin respectively.

5. Pulley-

Pulley is another version of a Wheel and axle where effort is applied through a rope or belt to lift the load with the help of a groove along the edges, known as Pulley.

The addition of two or more pulleys will greatly reduce the applied forces or effort with the same amount of load. As pulleys are known to be foece multiplier.

Types of pulley-

There are two types or kinds of pulley-

I. Fixed Pulley

II. Movable Pulley

I. Fixed Pulley-

A type of pulley which is fixed with any kind of shaft and does not move by any means is known as a Fixed Pulley.

Examples of Fixed pulleys are- Water well, Window Blinds, Pulley lights and Motor Pulley. 

II. Movable Pulley-

A type of pulley which can be moved on the shaft while carrying the load or without load is known as a Movable Pulley.

Examples of Movable pulleys are- Exercise Equipment, Theatre Curtains, Elevators, Exercise Equipment and Sails on sailboats.

6. Screw-

A simple machine wrapped with a spirally inclined plane in a shaft to convert rotational motion into linear motion is known as a Screw.

A screw is one of the most used mechanical device or simple machine just like nut and bolts.

Screws are used to join things together, hold things up or used in lifting heavy weights or loads.
