| Dec 14, 2020 at 9:26 | comment | added | pglpm | @Buraian Yes that's what they do. $\tau_{xy}$ for example is the force orthogonal ($y$ direction) to the normal in the $x$ direction. | |
| Dec 14, 2020 at 9:24 | comment | added | pglpm | @Buraian around the pulley the rope is accelerating laterally, that's why we find that $a_y\ne 0$ there. | |
| Dec 14, 2020 at 9:24 | comment | added | Brian | So, if I got this right, the cross components of the stress force denote the force which twists and bends the force being transmitted across the rope? | |

better description

| Dec 14, 2020 at 9:21 | comment | added | pglpm | @Buraian coordinate $x$ is meant to be along the rope, and $y$ orthogonal/lateral to it. So where the rope is perfectly horizontal or perfectly vertical, $a_y=0$, otherwise it would be accelerating laterally | |
| Dec 14, 2020 at 8:50 | comment | added | Brian | "The approximate analysis just made is also correct for horizontal or vertical segments of rope, away from the pulley. In that case we find that ay=0 and 0=Ry=Fy=Gy." , this part here if the acceleration is zero, then how is it possible that this rope moves through space | |

corrected figure
|
| Dec 14, 2020 at 7:19 | comment | added | pglpm | @Buraian Sorry I'll replace the figures. That's a thin segment of rope. The rope continues outside of side 1 and side 2 | |
| Dec 14, 2020 at 6:03 | comment | added | Brian | I'm a bit confused from your picture why is the rope coming at a slant height straight out of the pulley? isnt it hanging over the pulley? | |
