Input–Process–Output

Question 1

What does ‘input’ refer to in an input–process–output system?

Answer 1

The initial action or energy applied to the system to start a function.

Question 2

What does ‘process’ mean in an input–process–output system?

Answer 2

The mechanism or operation that converts the input into a desired action.

Question 3

What is the ‘output’ in an input–process–output system?

Answer 3

The final result or action produced by the system.

Question 4

Give an example of an input in a mechanical system.

Answer 4

Turning a handle or pressing a button.

Question 5

Give an example of a process in a mechanical system.

Answer 5

Gears rotating or a lever moving.

Question 6

Give an example of an output in a mechanical system.

Answer 6

Opening a valve or moving a conveyor belt.

Question 7

How would you analyse a mechanism using input–process–output?

Answer 7

By identifying what initiates the system, how the mechanism works internally, and what the resulting action is.

Question 8

What is a mechanical control application?

Answer 8

A system that uses mechanical parts to regulate or control a process, such as brakes or gearboxes.

Question 9

Name two examples of mechanical control applications.

Answer 9

Car brakes and bicycle gear systems.

Question 10

Why is understanding input–process–output important in designing mechanisms?

Answer 10

It helps in ensuring the system functions correctly and efficiently to achieve the desired outcome.
