Question

As simple as the ride seems, only advanced engineers can make safe and fun Ferris wheels." Can you think of any other machines that seem simple but actually are not? List at least two and explain why they are not actually simple

Answer 1

1. wash machine
it looks simple but an engineer takes a lot of time to make it

2. computer
it looks simple but is really tough to make it

Answer 2

Answer:

Automobile and centrifuge are examples of simple machines which are actually really hard.

Explanation:

Automobile:

• An automobile with a gasoline engine is a sophisticated mechanism made up of thousands of simple machines. Each rocker arm that controls the engine's numerous valves is a lever. The car has four wheels and two axles, and the timing belt is a form of pulley.
• The overall make-up of an automobile must sound easily understandable but the in-depth mechanisms used for the working of the automobile is tough and complex.

Centrifuge:

• A centrifuge machine is an important piece of laboratory equipment. It's a basic gadget that rotates at a fast speed to separate liquids of different densities.
• This is mostly used to separate blood components and conduct testing on them. This may sound easy to use and understand, but in reality the principle of the working of  a centrifuge machine is hard.

• A centrifuge works by using the principle of sedimentation: Under the influence of gravitational force (g-force), substances separate according to their density.
