Question about engine speeds/work

I also agree, but I dont 100% agree. If your in 1st and going 5 grand steady and you push the gas it will go like hell to the rev limit, but if your 5 grand steady at 130 and you push the gas all the way down it will slowly gain. My analogy is that you can bench press 40 Lbs 10 times a minute and you can also bench press 100 Lbs 10 times a minute but the heavier weight (gearing and resistence in 5th gear) will be more stressfull.
