Thanks. That's what I would have expected the drawing to look like in terms of the geometric tolerances.

I believe it's a bush which has a pin to fit inside of it The groove is for an o-ring to sit. If it was me, I would have made the id and od with a concentric tolerance, and put the parallel on the 57mm face

Thanks for all your replies. Note, this is not my original drawing, but one I came across, and you have confirmed my suspicions.

Thanks John, In reference to the parallelism, if the datum is the flat (top / underside, rather than side), then the 49mm dimension is actually perpendicular to this, not parallel. This was my understanding of it. I thought the parallelism would be on a face parallel to this, but i may be wrong

Thanks. Moved to the other forum, can close this one now

Hi I haven't used Geometric tolerances for a while, so I just wanted to double check I'm not going insane I stumbled across a drawing (see attached / or below post), and I'm pretty sure the geometric tolerancing is wrong. 1) The parallelism looks to be on a wrong face? 2) Also, personally I...

Hi Actually we do plan to make a test rig. It's just that my boss wanted me to provide some calculations on what I expect the answer to be prior to this. In his mind, he expects a huge resistance, which to me seems like a small miracle. We do intend to test at various cable sizes up to a 64mm...

Hi. thanks for your answers. Sorry, I should have given more detail. Let's say we are pulling the rope to the left in the diagram. The 200kg weight is hanging off the right hand side resisting. I just wanted to know if the force required would be 200x9.81, or more than that. Obviously it...

Please see crude sketch of red line showing rope path. Basically they asked me what force would be required to pull the rope through the snaking pattern, if say a 200kg weight was attached to the other end

Hi sorry, yes Newtons! Is there anyway to calculate or even approximate the resistance due to bending rope? I can't find / remember of any useful equations. I thought possible Euler's, or even "beam deflection theorem", but I think these are irrelevant

Hi I'm trying to explain, justify, calculate I have a cable that S-shapes under and over a series of pulleys, and I'm trying to calculate how much extra tension is required to pull the rope through the snakey pattern. In my mind, if the pulleys are frictionless (ie. bearings), then bending...
