anuttarasammyak replied to the thread A very simple moments question.I mean couple not moment. Thanks to #6 in usual case Blue forces couple and red forces couple cancel. My #16 confirms it. In the... -
anuttarasammyak replied to the thread A very simple moments question.Is the net couple zero in this system? The couple produced by the two forces in the x-direction is zero. However, it seems that the... -
anuttarasammyak replied to the thread A very simple moments question.Thanks. My thread examples were not appropriate. Net zero inhomogeneous x force act at the contact area of the remaining bar so that it... -
anuttarasammyak replied to the thread A very simple moments question.$$F_y=w-D_y$$ it can be negative, zero or positive. Some example cases $$F_y=w > 0,\ \ D_y=0$$ $$F_y=0,\ \ D_y=w$$ $$F_y<0,\ \... -
anuttarasammyak replied to the thread A very simple moments question.All external forces should be considered at the points where they act on the body. D is acting on point Q in the figure you show. But... -
anuttarasammyak replied to the thread Undergrad ##r-##independent angular momentum in quantum mechanics.Pursuiting the calculation I showed $$\hat{L}_z=-i \hbar \frac{\partial}{\partial \phi}$$ I am not sure whether it is consistent with...
