I have noticed a realy dumb mistake in the orginial example. It should say the following (updated numbers in bold italic)
"The lower bar is moved downwards until the two bars are 595mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm...
Thanks, happy to be here. Found PF looking for help, but I'll definately be hanging around.
So here we're I'm up to:
My first instinct is that if you have a force and an area, you have pressure? We’ve got 22.5N (You need to divide the 45N by two as we’re measuring two “legs”) and 0.3m2 which...
Scenario 1 (figure 1)
A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material.
The lower bar is moved downwards until the two bars are 1190mm apart...
