Chapter 20, Problem 20.1A

To determine

A.

What part does engineering play in the lives of people around you. Collect six examples that show the ways that engineering is an integral part of the everyday lives of the people.

Explanation of Solution

Engineers have innovated such a wonderful things which we use in our everyday life. Our life has become easy because of these inventions. Now we cannot even think of our life’s without these inventions.

Examples that show the ways engineering is an integral part of the everyday lives of the people:

1. Light bulb
2. Television
3. Remote control
4. Watch
5. Air conditioner
6. Fan

There are millions of things that we use daily and have become and integral part of our daily routine. We can’t even do a single day without these things they have become a necessity.

Conclusion:

Inventions of engineering are a boom for our society.

To determine

B.

To think:

From engineers perspective. What thought they had while working on those items. Did they consider the science and mathematics of the objects, or was there more.

Explanation of Solution

Now considering an engineer’s perspective while developing these objects. The only thought they had in their mind while working on these items would be to create soothing very beneficial for our daily life which would decrease our effort and which will give us some comforts. Which will raise our standard of living.

According to me in addition to the science and mathematics of the objects they might have considered that how people will use it, regarding its safety for use, its social and economic benefit, its durability, its long life etc.

Conclusion:

All the above factors must have been in an engineer’s mind while developing certain things.

To determine

C.

Are the latest models designed only for gas efficiency and aerodynamics? Do we really need rich Corinthian leather? Heated seats? Thermometers in the rearview mirror. Why is there so much chrome? Why don’t we build an efficient automobile? Why is it necessary to try to produce beautiful automobiles? Why are they appealing?

Explanation of Solution

No, the latest models are not designed for only gas efficiency and aerodynamics. Most of the people demand rich Corinthian leather as it adds to the beauty of the car. Engineers try to build an efficient automobile but every time they land in innovating something new so in their new versions they add those innovations. And moreover it depends upon the price of the car, they can’t use expensive material to develop an economy cars as everyone won’t be able to purchase it.

It is very necessary to produce a beautiful automobile as people gets attracted by beauty. They will not purchase an automobile that doesn’t attracts them. This is the reason engineers have to spend a lot of time in making their automobiles very attractive.
