Homework Statement


Some moron kids are trying to tip over a storage bin as shown. The bin weights 6950 N, w = 1.8, h = 2.8, d = 1.85, and theta = 22 degrees. With what force do they need to push in order to tip the bin over?

Homework Equations


T = R * F * sin(\theta)
\Sigma\textbf{T = 0}


The Attempt at a Solution


I don't want an answer, I want to know where to start... This is the first time I've been given a problem with Torque in the X direction and the Y direction. I just need somewhere to start from... I need help before 10:30, or I'm screwed... (Coefficient of Desperation)

Post the diagram so we can see what theta refers to.

Hints: What exerts the counter-torque that the kids must overcome? As it begins to tip, where is the pivot point?

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...
