How Fast Does Nitrogen Expand to Power Piston Arms?

AI Thread Summary
The discussion focuses on determining the expansion rate of nitrogen at various psi levels at room temperature to optimize the velocity of a piston arm. The user seeks to calculate how quickly the piston can move to achieve maximum speeds. There is a suggestion that slower movement with increased force might be more effective for certain applications. The importance of velocity is emphasized, as faster movement can lead to greater propulsion of objects. The conversation concludes without a definitive answer to the original question.

i'm trying to figure out the expansion rate of nitrogen at any given psi in room temperature. roughly in fps.

trying to calculate how fast we can move a piston arm to get maximum velocities

Im not sure on this, but may i ask why the velocity is so important? If you are looking at doing work with this piston it might be easier to simply move it at a slower rate, but with more force. (Heating the nitrogen to a higher temp, using more of it, ETC)

If that makes sense.

the faster the ram moves the higher the velocity can be reached to propel an object

Ah i see. Well, sorry i couldn't help you then. =)
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
