Graduate A rod in free fall with varying length
1) I assume that the rod is at rest. So the velocity is zero but I will keep the orientation of the rod free. However, I assume the motion is fully planar. 2) The length of the rod is determined purely by the internal forces so I the length of the rod, L(t), is a function only dependent on the... -

Graduate A rod in free fall with varying length
Suppose you have a weightless rod with at the endpoints two masses. This is a special rod whose length varies in time as a function L(t). If I consider this rod in free fall my intuition is that this rod will rotate for suitable L(t). However, I want to write down the equations of motions for...
