CRuD - Maybe with your overwhelming excess of common sense you could tell me by what percentage the tractor/lowboy was overloaded - based on it's GCWR? Nathan was ~150% above a 20k rating. I don't know the rating for his particular truck but it sure isn't 50k. I'd really like to hear your take on bending stress, shear stress, fatigue life and all those other topics that fall under common sense. Maybe you could explain to me & all the DC (and Ford, Chevy, Freightliner etc) engineers how to design things. Do you really think that a company that is trying to save money by eliminating bed side moulding and grab handles has designed in so much margin (that means EXCESS steel for you common sense folks) and not increased the factory ratings or charged the customer for it? I wonder why Ford offers the 450/550? Would it be because they have higher ratings and thus they command a premium price & fill the gap between a light duty P/U and a medium duty 650/750? I thought SWA was SouthWest Airlines
Greg - NVR FNSH is the license plate on my CJ-7. I'll never finish working on it. I'm terribly sorry that you have to work two jobs to afford your toys - luckliy I don't. BSME - Bachelor of Science in Mechanical Engineering. I really don't take myself seriously, ask the people who sit across from my college roommate & I. This just happens to be my pet peeve.
Diesel Freak - My curiousity is peaked - what do you do 'outside the city limits? Using the tools available, I see you're 28 - a few years younger than me. Can you pass on any career advice so I don't 'step in it' again? My degree is from Cal Poly, San Luis Obispo - ranked one of top PUBLIC schools in the country. Cal Poly is known for it's hands on education and graduating people that are ready/able to work. I take offense at your smart *** remark about 'only spent the money for it'. Would you care to cite the 'common sense' regarding a 50k GCWR? What have I missed? Was the frame modified to increase it's strength? How about the bolts that attach the hitch to frame - increased number to distribute the load? Explain to me where I made an error. Show me the data/calculations that our trucks can handle 43k over the design life and still meet DC's end of life/safety margins - I'll be the first to admit I am wrong. If I take it all back will you interview me if I get laid off? I promise to use common sense and the tools available to me in the future.
Have any of you seen the new (at least to me) F150 commercial showing the #66 truck blasting through the desert? That truck was designed by Light Racing, Inc and built by Baldwin Racing - big time home builders in SoCal - in '93/'94. Baldwin Racing built 3 of them at ~$250k each. Guess what? Your's truly helped design that truck. In fact, my senior project - required to obtain that piece of paper that only says I had the money to obtain a degree - was the rear suspension Rocker Arm (I'm looking at the dwg). Luckily, Baldwin Racing employeed several magical fabricators and I didn't have weld the darn thing together. I'm not that skilled. I guess helping to design/build A-arms & swing arm for my buddies race quad doesn't count for much. What about doing chase/pit support for that quad all the way to La Paz?
Can I go back inside the box now? Sure wish I got out from behind a desk more often. I've often wondered what it's like in 'real' world?
Oh, and my engineering co-op? Garrett Turbochargers in Torrance, Ca. I was testing silencer rings and Extrude Honed compressor housings before most of you knew what either of those were.
Nathan - all the load will still be transferred to the truck. The rubber bumpers & spring only reduce the shock (increases time of load application) to the frame. The load is still reacted by the truck frame/bumper.
Bull headed, don't know when to stop (especially when insulted) and damn proud of it.
