    Thahkyou very much for your depiction of all the necessary things at play in the weld /fab. World
    A curiosity has its moments of the various forces upon a tandem axle flatbed / car hauler. The notion of a hydraulic tilt or lifting of the front to ease the angle of approach. Based on a 20 ft. Flat bed . Where would a engineer such as yourself . Put a tilt hinge point at what location is most desireable for a 4000 lb. Auto to role upon a bed or to roll off with out major catastrophic damage or personal injury .. ?

      Short question, easy answer — It depends. I’m sure that’s not what you’re looking for, but how you approach the design makes all the difference. What is moving? How is the tilt supported? I’ve seen some where the axles move and the tilt pivot is effectively the hitch. Sorry, no way to give a concise/always true answer.

    This was an awesome article. I’m a professional welder but the engineering side is a another beast. I was asked to weld a trailer for someone. He wants to weld everything, no cracks, and grind the welds….. *hand meets forehead* ahhhh! So this has perfect illustration to why this is an issue. Ask a professional but doesn’t want it done right apparently. I obviously have some concerns with putting my name on something that could potentially fail do to someone else altering my work and kill someone. I’ve turned down many jobs because I hold a high standard to myself and what I do and would like to keep doing it. Thank you again for the read it will greatly help my safety arguments when I go into this.
