1. See following attatchment

2. Moment of force= (force)*(perpendicular distance) only for scalar problems.



3. Well i know that moments are a cause of roation among a certain point
and when computing equilibrium we have to calculate the moment for every force
on the free body diagram.
we need the magnitude of every force as well as the perpendicular distance from each force to point A. as shown in the problem. but i cannot seem to figure out what equation (s) I need. all i need is a little guidence not the answer. thank you

(What do yo mean by "only for scalar problems" ? :confused:)

This formula should give you the answers for this diagram …

what is worrying you about it? :smile:
 
Thread 'Need help understanding this figure on energy levels'
This figure is from "Introduction to Quantum Mechanics" by Griffiths (3rd edition). It is available to download. It is from page 142. I am hoping the usual people on this site will give me a hand understanding what is going on in the figure. After the equation (4.50) it says "It is customary to introduce the principal quantum number, ##n##, which simply orders the allowed energies, starting with 1 for the ground state. (see the figure)" I still don't understand the figure :( Here is...
Thread 'Understanding how to "tack on" the time wiggle factor'
The last problem I posted on QM made it into advanced homework help, that is why I am putting it here. I am sorry for any hassle imposed on the moderators by myself. Part (a) is quite easy. We get $$\sigma_1 = 2\lambda, \mathbf{v}_1 = \begin{pmatrix} 0 \\ 0 \\ 1 \end{pmatrix} \sigma_2 = \lambda, \mathbf{v}_2 = \begin{pmatrix} 1/\sqrt{2} \\ 1/\sqrt{2} \\ 0 \end{pmatrix} \sigma_3 = -\lambda, \mathbf{v}_3 = \begin{pmatrix} 1/\sqrt{2} \\ -1/\sqrt{2} \\ 0 \end{pmatrix} $$ There are two ways...
