actually, horsepower is just an expression for the speeds at which a device produces torque.
Look boss man, we are keeping it simple simple. No RPM and all that jazz. Just the basic what makes what. Takes horsepower to make torque.
I gotta try that someday. Spray starting fluid into the intake side of a running air compressor.
Take video.
My grandfather lost his thumb playing with homemade firecrackers, so it runs in the family.
problem for you is it isn't keeping it simple but sounding like a simpleton... ... it takes rotation speed and the torque produced at that speed of rotation to derive a horsepower calculation. 1000 pounds feet of torque with no rotation is zero horsepower.. 1 ft lb of torque at 5252 rpm is 1 horsepower.. 2 ft lbs of torque spinning at 2626 rpm is still 1 horsepower... 4 lbs feet of torque at 1313 rpm is still 1 horsepower... but zero lbs ft of torque at 10,000 rpm is still zero horsepower. try the math sometime..
If your driving along at 70 mph turning 1600 rpm if you look at the load on a scanner, it’s going to be under a higher load, than if the engine is turning 2000 rpm at 70mph. The engine isn’t going to be under the same load, it’s going to be under less load with slightly more rpm at the same speed.
Other way around. Actually it takes torque and speed at which that torque is produced to make HP. It's defined by the HP equation. Engines create only mechanical torque, and torque times the speed it's produced (RPM) defines the amount of horsepower it makes.
Not true, you got it backwards.
It's not just the journal bearings, but all moving parts that have an oil film between them. The higher the RPM, the more heat is produced from oil film shearing and friction. The differential is a prime example.
That’s what everyone thinks, that’s a question asked to the techs when I went to the Cummins classes for the ISV5.0 in the titan to get my certs so we could work on them. The question was how many people think torque makes horsepower everyone raised their hand. Reason it came up was bc he was explaining the reason for a V8 diesel instead of I6.
As explained, it takes torque at a rotational speed (RPM) to make HP. The HP equation defines it, and it's the only way to make HP. If you have a torque with zero RPM, you have zero HP. It can't be any other way.
Well go to Cummins and tell their professor they are wrong. I’m going by what the poor man taught a class of 30 technicians. See this is what I talk about with members. A professor teaches one thing and on here there is a discrepancy. That’s what I was always taught that torque makes horsepower.
No one cares what you heard from some dude teaching a mechanic’s course. Basic Newtonian physics dictates this. High school or college level first semester physics.
You're saying two opposite things now (see bold).
We weren’t there to discuss what you’re talking about. We were there to learn that particular motor and the ins and outs of it. What to look for on a diag, some problems you may run into with this particular engine, how to know if someone tunes them all that good stuff. We didn’t go there to learn about HP and TQ
That’s all well and good, but then why confidently respond when you’re wrong and argue textbook physics?
