Yes those are the parts that are modeled.
FEA takes all the guess work out of the conversation.
It has no bias, no ego, no opinion. It is what it is. You draw the parts, assign a material type, constrain the part, and apply a load.
Again, what is not known is how the aftermarket parts...
Of course you fella's are right, but I don't understand making it easier for them though. Don't just submit and say "No matter what you do....."
If the app is free... you don't want it.
Fuelly.... with respect to actual mpg... isn't doing anything you can't do with a pen, a note pad, and a calculator.
Wait, no, I'm wrong. The pen, note pad and calculator isn't spying on you, tracking your driving habits and location and then selling that data and your information...
Folly? Our FX4 is bone stock, except for some rock sliders, we consistently get 27 mpg or better.
That's not over a couple thousand miles, that's over 17,000 miles at 8,200 feet elevation.
Hand calculated.
Yep... see... it's not folly at all. Your changes hurt the mileage.
In the realm of Ranger aftermarket exhaust systems, that's one of the better sounding one's.
And that's coming from a guy who hates pretty much all the aftermarket Ranger exhausts.
Highly unlikely.
The moment of inertia of a rectangular section is based on the face width dimension to the 3rd power.
Decreasing the tube size drastically compromises the strength,
Increasing the thickness has a much lesser effect in increasing strength.
In Aug 2020 we did a road trip in our FX4 SuperCab, about 9 hours of driving. What I'm finding is setting the cruise control @ 65 mph is the "sweet spot" for good mpg, we averaged 28 mpg.
Anything faster and the mpg stars to drop
More likely an issue for those that simply remove the existing crash bars without replacing them. Kind of like removing a supplemental restraint device, like seat belts or an air bag, but to a lesser degree.
If you replace the intrusion beams with aftermarket units that fail and cause a...
here's a crash test... on the passenger side.
The best way to view this is to set the video playback speed to 0.25 using the tool icon in the bottom right of the You Tube screen. Then go to:
0:08. The tire hits the barricade, it goes flat and it drives the wheel into the wheel / foot well...
