    I am trying to lend some help to one of the guys at my company who is not a member here. He is working in Solidworks 2011 for the firs time and is struggling with the lines. From what he and I can tell, you can only have solid or center lines. Is there a way to draw hidden lines / dashed...

    RTV - Waterproof

    What do you all think about using rtv as a waterproofing agent? I've got a small potted pressure switch that is only IP65 rated. Problem is, I need to submerge it (IP68 rating), and it does not quite work that well. For the most part it is waterproof, but there is one small press fit square...

    Matschinsky - Road Vehicle Dynamics?

    Has anyone here had any experience with the book Road Vehicle Dynamics by Matschinsky? A friend told me it is a very good book, and would round out my library nicely. I already have books by Olley and Milliken.... Any thoughts? Is it even worth the high price tag? No real reason to getting...

    Has anyone here ever worked with the GK subsidiary known as Active Shock in a heavy vehicle application? If so, what can you tell me about them?

    Torque Values (Rule of thumb?)

    Here are the 2 bolted joint scenarios I'm looking at. 1. I have a 1"-14 bolt with a maximum service loading of 8,880lbf. The bolts are black oxide coated so I'm using a k factor of .25 - .21. My calculations show that I need torque values ranging from 714 ftlbs to 850 ftlbs to obtain the...

    Light Duty Truck Air Ride Suspension

    I'm looking to put an air ride suspension on a Ford F550 Cab Chassis. In doing my research I have found a few main players whose product I might choose from (Link, Kelderman, Reyco Granning, and Monroe). For the most part the designs for their air ride suspensions look relatively similar...

    Heavy Truck Lateral Acceleration Dynamic Load Transfer

    Perhaps this is a dumb question, but my fellow engineers and I are drawing blanks on a potential issue... First off... We are working with a fire truck that has a water tank attached to the top of the vehicle, which throws the CG way out of whack... So, for ease of calculations, we are assuming...

    Lateral Braking Force At Tire Patch

    Perhaps this is a rather elementary question, but for some reason I am being forced to second guess my self. I am relatively green to the vehicle suspension industry, and am trying my hardest to learn as I go. I will be attending some seminars in a few weeks that will help, but until then, I...

    Barrel Spring Unusual Failure

    This could be a tough question, but any input would be much appreciated. I have a barrel spring that had some strange failures recently. We had 2 out of 8 springs fail at about a quarter of the test time at the OD of the part. Typically if we see an early failure it will be on the ID and is...
