I've been measuring and testing approach, departure and breakover angles, and this is what I've discovered: 1. A truck can't begin to climb, without scraping the front low spot, any slope steeper than it's approach angle. Doesn't matter if the slope is short or if it's long. 2. A truck can't exit, without scraping the rear low spot, any slope steeper than it's departure angle. Doesn't matter if the slope is short or if it's long. 3. When approach angle exceeds departure angle, a truck can't climb a slope, without scraping it's rear low spot, that is both longer than it's wheel base and steeper than its departure angle. 4. When approach angle exceeds departure angle, a truck can climb a slope greater than the departure angle, without scraping anywhere, provided that the slope angle is less than the trucks approach angle and less than it's break over angle and the length of the slope is less than the wheelbase of the truck. 5. A truck can't fully exit nor descend a slope, without scraping the undercarriage, that is steeper than it's breakover angle. 6. Approach and departure angles change when driving down a gully and up the other side. Again assume approach angle exceeds departure. When the truck starts up the opposite side of the gully prior to the rear of the truck leaving the descent slope the departure angle will be reduced when the front tires reach a height greater than the rear tires. In other words, the decent hill must be less than the departure angle. Also the approach angle is reduced when the rear wheels are higher on the slope then the front wheels. As such the slope of the exit side of the gully must be less than the approach angle to avoid hitting the front of the truck.
I like your accent. It is partly Spanish, British, or German together, of course you do not expect that, Saludos from Costa Rica. By the way may I use break over instead of ramp angle? Gracias

Thats some in depth research you've done there. I agree with what you have concluded. Thanks for sharing with us. MadMatt
5 is wrong, break over doesn't come into play exiting descent, it can't enter the down slope, Einstein. likewise vice versa
Very nicely explained sir thank you so much
very well explained and live demonstration of most important offroading angles.. usually people just talk with pictures which makes zero sense !!
Thanks. That’s my first ever video.
MadMatt 4WD great going!! All the best mate
Best explanation - you have explained it very well. Thank you
My pleasure. This was the first video I ever did.
love your work Matt
Good explanation.🚙
High quality video for way back in 2013.
Thanks. my first ever
Excellent 🎉🎉
Thank you! Cheers!
Excellent videos. Happy to subscribe

LOL yes you may use break over angle.
really helpful
Thank you for uploading
I watched this to the end for the whistling
Love the commitment.
Thank you bro
why is that 5 lug?
It’s a 100series landcruiser which run 5lug standard.
DONT BE AFRAID TO BUILD TRACK TO LESSEN DAMAGE TO VEHICLE
watched the vid, seen definitions and illustrations and no tips, as the title claimed. this is the only useful tip on this page
It's very uncomfortable to see this guy putting his head and hands under a 4x4
Really?
@@MadMatt4WD Yes, very scared of an accident=
