Simple machine and complex Md. Jobayer

What is machine?

Ans: A machine is a thing that is created by people to make work easier.

What is simple machine?

Ans: A machine with few or no moving parts that is used to make work easier

What is complex machine?

Ans: Complex machines are also called compound machines . Two or more simple machines work together to form a complex machine. Compound machines can do more difficult jobs than simple machines alone.

what is machine 

 A machine is a thing that is created by people to make work easier. It is a tool or invention which multiplies the effect of human effort. The machine produces a mechanical advantage. ... Often a machine will change one form of energy to another form of energy. Simple machines increase or change the direction of a force. 

what is simple machine

Simple machine is a A machine with few or no moving parts that is used to make work easier (provides a mechanical advantage). For example, a wedge, wheel and axle, lever, inclined plane, screw, or pulley.

what is complex machine

Two or more simple machines work together to form a complex machine. Compound machines can do more difficult jobs than simple machines alone. Examples of complex machines are bicycle, wheel barrow, crane, car jack, lawn mover etc.

What is a machine in simple words?

A machine is a thing that is created by people to make work easier. It is a tool or invention which multiplies the effect of human effort. The machine produces a mechanical advantage. Often a machine will change one form of energy to another form of energy. Simple machines increase or change the direction of a force.

What is machine used for?

Machines can be simple, like a lever or pulley, or they can be more complex, like a computer or an automobile. The main purpose of a machine is to make things easier for people, like lifting and moving heavy objects around, working out a mathematical equation or even ordering food from a restaurant.

What is type of machine?

machine: Types of Machines

Thus defined, such simple devices as the lever, the pulley, the inclined plane, the screw, and the wheel and axle are machines. They are called simple machines; more complicated machines are merely combinations of them. ... The wedge is a double inclined plane.

Is computer a machine?

A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations automatically. Modern computers can perform generic sets of operations known as programs. Early computers were meant to be used only for calculations.

Who made machines?

The complete dynamic theory of simple machines was worked out by Italian scientist Galileo Galilei in 1600 in Le Meccaniche ("On Mechanics"). He was the first to understand that simple machines do not create energy, they merely transform it.

what is machines? 

machine is  three types simple,complex and compound machine.machines are used to make our life easyer.now a days people canot stay one day without machines.machine can do every things what we will tell him to do .a machine is any physical system with ordered structural

complex machine is a machine that's  makes our life easer to work .with complex machine we can do hard thing easily . heavy things we can carry easily .   we can do so many heard    thing easily with two simple machine can make one complex machine.

 

how machine works ?

Machines simply transmit mechanical work from one part of a device to another part. A machine produces force and controls the direction and the motion of force, but it cannot create energy.                  

what is the work of a machine?

The operation of a machine may involve the transformation of chemical, thermal, electrical, or nuclear energy into mechanical energy, or vice versa, or its function may simply be to modify and transmit forces and motions. All machines have an input, an output, and a transforming or modifying and transmitting device.

how machine helps us?

When a force is applied over a distance, it produces work. ... It also takes twice as much work to lift the same object twice as far. As indicated by the math, the main benefit of machines is that they allow us to do the same amount of work by applying a smaller amount of force over a greater distance.

 What is machines?

A machine is any physical system with ordered structural and functional properties. It may represent human-made or naturally occurring device molecular machine that uses power to apply forces and control movement to perform an action.

Why we need machines?

Simply put, machines have integrated themselves into our daily lives and now play a prominent role in our society. We have almost completely substituted all previous forms of communication, transportation, and other aspects of our society with the creation of newer, more industrial methods and apparatuses.

What are the two types of machines?

Machines come in two kinds — Simple Machines and Complex Machines. A simple machine is a tool, device, or object with few moving parts that help us do work. Simple machines have been in use for a very long time. Early humans used simple machines to push, pull, lift, divide, and crush things.

What is complex machines?

Complex machines are also called compound machines. Two or more simple machines work together to form a complex machine. Compound machines can do more difficult jobs than simple machines alone. Examples of complex machines are bicycle, wheel barrow, crane, car jack, lawn mover etc.

What is simple machines?

simple machine, any of several devices with few or no moving parts that are used to modify motion and the magnitude of a force in order to perform work. ... The simple machines are the inclined plane, lever, wedge, wheel and axle, pulley, and screw.

What is machine?

A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations automatically. Modern computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. 

What is the role of computer? 

Computers play a vital role in every field. ... Owing to memory capacities of computers, large chunks of data can be stored in them. They enable quick processing of data with very less or no chances of errors in processing. Networked computers aid quick communication and enable web access.

How computer works?

A computer system works by combining input, storage space, processing, and output. ... For example, when we type something using a keyboard, it is known as an Input provided to the Computer. Storage Space: It is the place where our input gets stored. It is known as Computer Memory that keeps the data into it.

How computer is useful for students? 

Computers have become important in school and college education because they provide access to such a huge variety of information. While students of the past had to rely on textbooks, these days information can be found quickly and easily online.

SIMPLE AND COMPLEX MACHINES

Machines are some things that helps us a lot in our daily life and make our work way easier. 

Machines come in many shapes and sizes but there are mainly 2 types of machines, The two main kids of machines are Simple and Complex machines. There are mainly 6 types of simple machine. The six different simple machines are Lever, pulley, inclined plane, screw, wheel and axle and Wedge.
