Question

What is machine ?????¿???????​

Answer 1

Hey there!

What is a machine?

↪ A machine is a device which helps to overcome a large resistive force by applying a force in a convenient direction.

Different Terms Related To Machine -:

1) Load- It is a large resistive force to be overcome by a machine.

2) Effort- It is a force applied on the machine to overcome load.

3) Mechanical Advantage- It is the ratio of load to effort.

4) Velocity Ratio- It is the ratio of velocity of effort to the velocity of load.

5) Input work- It is the work done on the machine by the effort.

6) Output work- It is the work done by the machine on load.

7) Efficiency- It is the ratio of output work to the input work done in the machine.

What is the principle of machine?

↪It states that the output energy is always equal to the input energy for an Ideal Machine.

Answer:

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.
