I have the following setup:
The string of negligible mass, causing little friction, is shown in dark blue and is fixed at the red circle. The taut string is shown in light blue (with excess string removed). I have shown an orange arrow which indicates the direction in which the string is being pulled. Importantly the force is always exerted at that location and any excess string is removed.
I would like to know how the string deforms over time as it is pulled from that point (orange). Does the end closest to the pulling force move first and straighten up, wrapping around the object 'A' early on, or does the whole string change shape continuously?
How does the direction of pulling force affect things if at all?
Thanks in advance.
