  You know your vehicle is having fun when it's toes curl.

  I was designing an extremely long hydraulic cylinder and I found out there's at least three buckling equations, the johnson, cosine and eulers with eulers being the only one they teach in school. Each equation is suitable for a particular slenderness ratio and investigating each one can save you from an overly optimistic result

  the lesson learned here is to get your moneys worth out of your windshield by not cleaning it until it miraculously fails all together.

  I work in the rack and pinion rebuilding business , they put those necked down sections as a &quot;fuse&quot; to control what fails.

  &quot;Engineering didnt answer any questions. It helped in no way. And I have learned nothing. But I didn&apos;t die...&quot; greatest quote of all time.

  When I almost broke my neck in 2nd grade, the whole class made &quot;get well soon&quot; cards for me, and one has stuck with me through the years. It said, &quot;Dear A.J. Please Don&apos;t Die&quot;. <br>So this is my message to you... Dear Matt, Please Don&apos;t Die.

  That 45 degree angle was tough to watch.<br>I could have sworn it was going to roll over

  Catastrophic Buckling was the first, and hardest, graduate course I took and our book was last published in the 1930s I&apos;m pretty sure because no PhD ever wanted to dedicate their lives to such a difficult subject ever again. Because the tie rod end doesn&apos;t apply a load at the exact center of the tie rod axis it decreases the force needed to buckle significantly (there are some kind of maths on this) since it induces a small bending load.

  There is a fourth way and my favorite way to calculate buckling. Have the DOD pay for material and just simply do destructive analysis. Makes the presentation very easy basically &nbsp;&quot;too long, make it thicker because...this&quot; <br>&quot;ooooh, how much thicke?&quot;<br>&quot;thickerrr.....i can find out exactly how much more down to the gram so you can maximize strength, lower weight, and mathematically significantly lower cost. But that might be about 2 years of R&amp;D with a 10mil &nbsp;budget....faster with more money...with what we currently know&quot;

  Proper off-road mechanical fuse replacement procedure:<br><br>1. Identify the mechanical fuse through properly neglecting the spotter and finding a rock the hard way (as Matt did.)<br>2. Use a very sketchy method to return the vehicle to 90% of safe operation at the trail head. &nbsp;Possible methods include: ratchet straps, welding using jumper cables, two batteries and 10 year old muddy welding rods, nearby forest lumber, etc.<br>3. Buy and replace both right and left fuses despite only breaking one.<br>4. Throw old un-blown fuse into spare parts box in the back of the off-road vehicle <br>5. Go find new ways to come close to soiling your underwear off-road, knowing you&apos;re fully prepared in case of another blown fuse!
