### Subject:Mechanical Engineering

Question:

As a mechanical engineer, the only thing i think is how we can increase the efficiency of a car engine?

Inactive

There are different theories about that. But maximum efficiency that is achieved by now is 60 percent. Why it is so? I have also done some research on it. There are different factors that effect the efficiency of a engine. And the main factor of low efficiency is heat losses. So if we are able to control these heat losses somehow, we can create more efficient engine. And is will be done in near future.

Question:

If we have some kind of effect on a small portion of selected area and we want to calculate or determine that effect over the complete area so what will you do as a engineer or what kind of calculation you will do?

Inactive

Well. As, a mathematician i will use different laws of math to do this. As, math is versatile, it has solution of every problem. If i look the above problem as a mathematician, I will use different laws over the area. i will form some relation and mathematical equations for that specified area and then integrate it over the complete surface. This is not necessary that our calculations are completely correct. But we only make assumptions to do calculations in the world of science.

Question:

This question often freeze my mind when I think what i see when i look up in the sky? Is it the past or i am seeing present?

Inactive

The answer is that we see the past when ever we look into the sky. Actually, when we see some kind of light travel from one place to an other in the sky, we are seeing it after years. As you know the universe is versatile, so it take a lot of time to travel in it. As, something happens in the space, then it's effects reaches us after a long time due to distance. That's why what we are seeing in the sky is just the past, it has already happen
