Sorry I don't think I fully understand. I assumed that the Stress (pressure) would be equal, isn't that a correct assumption even if the areas are different? Why would this mean that we have to assume all the strain is taken by the rubber?

Hello everybody, Here is a problem I have. QUESTION: The main span of a bridge has a length of 473 m. On each end there are the expansion joints like the one on the photo below. One day the city changed from -4 to +15 degrees between 6 in the morning and 2 in the afternoon. At 6 in...

Hello everybody. The concept of internal energy of a real vs ideal gas has perplexed me. From what I understand, an ideal gas solely considers the kinetic energy of gas molecules (temperature) where as real gases consider kinetic energy of particles in addition to potential energy. So...

And also, what will prevent the rocket from rolling, I intend to put a little compartment on the body of the rocket and I would like it to stay on top during flight. Is that realistic?

Great, now I am considering a parachute, it will be pretty easy to make and I was thinking to attach a string to the rocket and to the ground so when the rocket reaches a certain distance, the string will get taught, which would pull a hatch that will release the parachute. Does it sound do...

What would be the optimal center of mass?

Thankyou for all your help everyone I am now interested on knowing the actual physics behind the tailfins. How to they actually stabilize the rocket?

I am a little concerned about putting the egg on the front of the rocket to be honest. My current questions are 1. Is it not a good idea to put the egg in a tube above the rocket that will use the whole rocket's length as a crumple zone? (My issue is that the added weight on the back will...

So my biggest concern at the moment is the egg, in terms of resisting impact force, I am adding a giant crumple zone as the nose of the rocket. Does anyone have any experience with protecting eggs from impact. I considered perhaps putting the egg in some sort of light weight jelly. Is that a...

Hi everyone, My high school class is doing a competition where we have to build a rocket out of a 2L pop bottle powered by compressed CO2 and launch it (not directly up but at an angle) we need to... -achieve maximum distance -have minimimal horizontal deviation -protect an egg that the...
