OK everyone, I'm attaching the Newtonian and Langrangian equations of motion... Aside from a discrepancy with one negative sign (whoops) they are identical under these conditions: -In Newtonian, the spring force varies with the Sin(theta) (written in terms of y and the width of the system)...

Thanks for the replies everyone! I must admit that I'm not a student, I am an adjunct Professor at a community college, teaching Engineering Dynamics. I understand how the book says to solve the problem: here's my issue: We arrive at the Conservation of Energy by integrating the conservative...

Homework Statement Hi everyone, I am generalizing the following problem because I disagree with how the book solves the problem. A square mass 'm' is attached to two springs with identical constants 'k', in a configuration such that the springs mount to the left/right sides of the...

OK, I am thinking of the projection of a shadow onto a piece of paper, mapping 3D to 2D. Can you point me in the direction of the equations/theorems that explicitly give these extra dimensions units of length?

also I didn't mean to imply that I WONT read the material you provided... :) I will be reading that to see if it explains things a bit.

thanks for the reply! I glanced the link you gave (I obviously haven't thoroughly read it) and it illustrates my issue perfectly... The graphics shown with a large boat fitted into a canal contrast with a small boat moving in two dimensions supposedly "contained" within the canal is...

Are "small" extra space-time dimensions represented correctly? This is my first post, I searched briefly but I apologize if this is a commonly covered topic! The following is written in the spirit of the "aether" -- that, being an overcomplication with no evidence. One of my biggest...
