For example two off-the-shelf 12VDC power apdaptors that you plug into the wall. If I connect the +12V wire from one to the ground line of the other, am I going to get 24VDC or am I going to get a fireworks show?

The Montreal Protocol contains provisions to reduce the global amount of ozone-depleting substances. What is the role of engineers in the implementation of the Montreal Protocol?

Chemists discovered the issue of ozone depletion, and it seems that engineers are forced to abide by these regulatory provisions.

I still think that engineers contribute to enhancing human activities, in this case, the well-being of the protective ozone layer.

Thank you.

Do 4 fins offer more stability or 3 fins? I'm using cardboard or some type of light weight board to construct the fins. Based on y opinion, I believe that 4 fins will offer more stability due to more surface area, but I would like to hear other opinions. I am building a water rocket btw

What type of tool and associated pressure would it take to punch a 7/8" hole through a standard 2x4 stud? Ideally, it would produce a single "cork" of wood. Of course, there will be follow-up questions but please take a shot at this one.
