Classical Mechanics, Motion under Gravity, Motion on Inclines

AI Thread Summary
The discussion focuses on the importance of selecting appropriate coordinate systems in classical mechanics, particularly in problems involving free-falling bodies and blocks on inclines. The contributor shares their experience of revisiting these problems with different coordinate systems to illustrate their impact. The mention of caffeine-induced late-night insights highlights the creative process behind problem-solving. The conversation briefly touches on a cultural reference from "The Exorcism of Emily Rose" regarding the significance of late-night hours. Overall, the thread emphasizes the educational value of understanding coordinate systems in physics.

I had a brilliant idea last night at 3am (why do all brilliant ideas seem to come at 3am when your mind is racing from injesting far too much caffine during the day?) to include a couple of examples using different choices of coordinate systems. So, I did the free falling body and block on incline problems again w/ different coordinate systems. This will hopefully show the impact of choosing an appropriate coordinate system.

Anyway, here goes, and this one is it, done, finished, final, fertig, fini, finito, terminado, befejezett, обработанный, 出来上がる:bugeye:

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

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 '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...
