steering rack build - the FSM way?

Pete said:
The reading should be taken whilst the pinion is rotating at a constant speed. As you have mentioned the force required to overcome static friction is generally greater than the force required to maintain constant speed against dynamic friction forces, it is normally these dynamic forces that we are interested in therfore convention is to measure torque at constant speed. Glad I could help.

That was what I was inferring in my previous post. You don't get much of a window of opportunity to spin at a "constant speed" until you run out of rack travel, do you?

What this requires is a practical demonstration of your expertise. Something like one of those Royal Society lectures, perhaps? I want to see you rig up an experiment where you run around the table whilst taking your constant speed reading. Maybe with a Go Pro on your head?

You've worked on one of these racks before, right?



If you need any forum quote formatting help, just ask.

FFS, just pull the gauge and see what number it gives. You're trying to measure the torque on a 50 year old steering rack, not land a rocket on Mars.

Let's see who's been paying attention. Who can tell us what Franky's gauge will be reading in the above senario if his rack is in spec?
