    HP gains from switch to electric cooling fans?

    Although there is little more to add with regard to 92xj's original question, except perhaps that no-one has mentioned possible reliability concerns, I thought it was worth mentioning that some automotive suppliers are looking seriously at moving more and more ancilliarys away from the FEAD in...

    Prop Shaft Failure due to big angle of deflection..

    Oooh, tracks... Whats the torque transfer like? What I mean is, is the torque constant and smooth or does is peak up and down with bad reversals? I would imagine a metal track would be anything but smooth along a hard surface. I would imagine such vibration would play havoc with the spiders...

    24V Charging System Voltage

    Usually vehicle elctronics here in Europe are rated at 32Vmax and 24V nominal. Bear in mind that the actual voltage can go down as well as up so design for a range of about 17-32 if the electronics are critical. (ie, need to be active when starting etc)

    Stacked Plate Radiators

    I am far from an expert as you guys probably are, especially Des, but correct me if I am wrong in thinking that, a series of tubes has more surface area than a 'plate'? Furthermore, isn't it an advantage of modern style tube-type (for want of a better expression) rads that the tubes han be...

    Ackerman & Steering Effort

    Yeah sorry, I thought I'd mentioned that but reading back I didn't. It is a solid beam axle with the hydraulic steering ram mounted along the beam of the axle. There is not really any justification for a full suspension model in my view. One; because we can't afford the time or expense, and...

    role of shocks in heavy on-highway trucks

    Shocking! (sorry) What kind of trucks are these? What do they transport? Rigids or semis? Not that it matters really, but you (they) are asking for serious trouble. Bad shockers have a major affect on ride, and especially braking. The axles can vibrate enough under braking to cause the...

    Prony brake design

    A 'Prony' brake Greg is basically a band brake. Brake horsepower is calculated by measuring the difference in tension on each side of the band to give work done, and relating it to motor speed to get power. Well that's the basic principle anyway... It's named after the guy who invented it, I...

    role of shocks in heavy on-highway trucks

    Definitely need dampers. Air suspension systems can be designed with a certain degree of damping in the system by introducing a fluid and some complex valving, but I am unaware of any systems on HGV's on the road at the moment. Are you saying that your 'mechanics' are removing shockers from...

    From a solid model to PS orthographic drawing

    Gotta say I'm with Mike on this one, it doesn't get much easier that solview/draw for ACAD IMO. Although Alex's way works lovely, you still have to mess about creating, aligning and scaling your VP's whereas soldraw is just bish-bash-bosh, 3 ortho views, justlikethat, haha. Plus with the...

    Subtract function in 3D

    I've had this error before, it's a real pain in the arse. it usually occurs when the two objects have a complicated interface boundary. Where there are two edges not quite in line with each other, or if one or other of the shapes has had lots of ops performed on it. I think in your case, some...

    Creating a tif image from AutoCAD/Getting good quality?

    Go to the Adobe website and download a PDF printer driver (for free), install it as a windows printer and use it through autocad to create PDFs. This is the cheapest way I know (cos it's free) [2thumbsup]

    Multiline text in acad2000?

    ...or is the text direction set to vertical? You can check this in the properties box (ctrl+1). Make sure it's set to horiz (not by style).
