Why don't nuclear subs use electric motors instead of steam turbines?
nuclear power makes hot water which turns into steam. instead of turbine how about a generator..
Advantages and disadvantages of solid modeling using cad?
It has become common for people to rely on CAD and its analysis tools too much.
Instead of knowing what they are creating they just build and analyse and without understanding the problem the answer might not be right because they dont understand it.
I call these folk CAD monkeys. They get told what to do and they do it without any real knowledge or understanding of what their designing.
CAD is a means (a tool like a hammer) not and end. If I look something common for an example, a car for instance. The car is CAD, the driver is the CAD monkey. Everything works fine until the car breaks down. We then flop around like idiots wait on the AA to fix the car.
The point im trying to make is back in the day before CAD people knew how to do things in their head. But now for the most part were becoming lazy because the knowledge is all freely available we think we dont need to work for it. But we really do.
In the case of the car. We need to be the driver but also be the AA man (or woman if your lucky)
What is the role of electrical engineering drawing for material engineering field?
One of the customers of a material engineer is an electrical engineer. To understand the customer and what he wants, a good material engineer needs to learn the basics of how to communicate with the customer. Engineers communicate through drawings so that means a material engineer needs to learn how to read/create electrical drawings.

How do you find the thickness of cylinder?
External diameter minus internal diameter will get you the difference and then you have to divide by two to get the wall thickness. (as the difference in diameter accounts for both sides of the cylinder)
Can tolerance cause a overdose?
Only if you take more of a certain medicine to try to overcome the tolerance. Be careful!
What is the format for calling out a tapped hole?
It's done a few different ways, but the drawing will usually specify the hole size before tapping, the diameter and thread per inch of the tap, and the class of fit such as 1b, 2b, or 3b.
