Comparing the Internal Energy of Gasoline and Hydrogen

AI Thread Summary
Calculating the internal energy of gasoline is straightforward due to its stable properties under varying temperature and pressure. In contrast, hydrogen's internal energy fluctuates significantly with changes in these conditions. The discussion raises questions about the energy output of hydrogen compared to gasoline, particularly whether equal volumes of both can yield comparable energy. Understanding the energy density of hydrogen versus gasoline is crucial for evaluating their efficiency as fuels. Overall, the conversation emphasizes the complexities involved in comparing the internal energy of these two fuels.

Calculating the internal energy of gasoline is fairly simple, because it wouldn't vary much with temperature or pressure.

For hydrogen, though, it would vary significantly with each. What sort of ranges would we be looking at?

I'm curious if it would be possible to get the same amount of energy from hydrogen as it would be from an equal volume of gasoline.

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
