    Would it be easier to pull a train with flat wheels?

    Yes, I agree the weight of the machine will not hold in place with only gravity. However, the coefficient equation implies that it will.

    Would it be easier to pull a train with flat wheels?

    There is more then 1 pneumatic cylinder. I removed the top of the assembly including all other cylinders from this image. The total force produced from the cylinders is going to be about 20,000lbs. The tracks and wheels will be covered to eliminate any chance of oil. The answer i am...

    Would it be easier to pull a train with flat wheels?

    Danger.. You're killin me! That was a prototype in the first picture. The entire machine will be a weldment after all the bugs are worked out. :smile: Here is another image. I added a mock weight for reference and the cylinder will produce approximately 20,000lbs of force against a...

    Would it be easier to pull a train with flat wheels?

    Yes, this weldment only exists on my computer. However, the weldment will be built in a couple weeks. I am trying to give as much information as possible, but if I uploaded the file my boss would hang me. I will muck something similar and try to upload. Sorry to sound squirrel.

    Would it be easier to pull a train with flat wheels?

    This is an excellent analogy. Describes what I am trying to accomplish very well.

    Would it be easier to pull a train with flat wheels?

    Yes! That is exactly what the engineer said. It just doesn't seem logical. I believe the information, but a car with a larger contact patch is known to have more traction. Racers always want a wider tire apposed to a skinner tire. That was a great answer, the engineer I am working under is...

    Would it be easier to pull a train with flat wheels?

    I am not offended :smile: Let me try this again. The train was just an analogy to describe an object readers would be familiar with. Here is the situation: I designed a very large weldment which rides on 6 steel wheels sitting on a steel track. (much like a train) I have pneumatic...

    Would it be easier to pull a train with flat wheels?

    In both cases the wheels will not be allowed to rotate. ( I forgot to add this in the first post) The wheels will be fixed; therefore, no rotation will occur. With the wheels not able to rotate, will the train require more force to move with flat spots contacting the track or the small...

    Would it be easier to pull a train with flat wheels?

    A train applies steel wheels to a steel track. Therefore, without any distortion of the wheel or track, the contact patch would be extremely small. Now, if you slice a chord from the wheel, creating a flat spot contacting the track, the result is a larger contact patch. With a larger...
