Hallo TSny, Indeed the equation you derived is correct and matches the angles calculated from the program/sketch. Many thanks for your input. I neglected to consider in futher detail the segments on the vertical axis. Much appreciated and Thanks!

Hello All, I struggled to find a closed form solution connecting the 2 quadrants via the angles alpha and beta. I filled the schematic with right angle triangles hoping to find a connection but to no avail. In the end, I decided to create a polynomial function of beta in terms of alpha as I...

It does not render when I use the preview button. I have read a few threads on this. Seems to be a common problem unfortunately.

Not sure how to rectify this. Any ideas? It looks correct via the codecogs website (https://latex.codecogs.com/eqneditor/editor.php) \begin{align} (S \circ R)^{-1} & = \left\{ \left< z, x \right> : \left< z, x \right> \in S \circ R \right\} \\ & = \left\{ \left< z, x \right> : \exists...

Dear Experts, Currently I am reading up on Special Relativity. I struggle to understand how from the perspective of the Muon that the distance to the surface of the Earth is contracted and thus more Muons arrive at the surface based detector. How can this be? To me the physical space is real...

Hi Folks, Problem Statement How would one use the conservation of angular momentum to explain the attached picture? The rod is held fixed horizontally..the person holds on to the cork and then let's go...apparently the glass is saved due to this conservation... Relevant Equations Momentum...

Ah...I understand... homework TYPE questions. Ok. I will know in future! Can this thread be moved or shall I repost? Thanks B

Hi. I am not a student and this is not homework. I am reading physicsnin my spare time and occasionally I put a question up to get peoples opinions/help. Please advise how I should proceed for future queries.. Thanks B

So in laymans terms if I was to describe a situation to my friend about stopping a 18stone rugby player in his tracks by a sufficient tackle..which would be more appropriate...the energy approach? Or perhaps both are equivalent because to stop him covering more distance instantly is equivalent...

How should I look at the problem at stopping a moving object with the following conditions 1) mass m and speed v 2) 0.5 m and 2v 3)0.5m and sqrt 2 v Simple math tells me the number 2 would require more energy to stop it. I can relate to energy better in terms of how to stop a moving mass...

Then under what conditions does this Torque =inertia times alpha hold that one typically sees in textbooks?

Hi Guys, I have a simple annulus of radius 25mm and 15mm of length 50mm where i applieD a torque of T=100000Nmm. Its inertia about its main axis is I=124.9 kgmm2. Therefore i expect the acceleration to be T/I. Its not clear how to confirm this answer in Msc Adams because when i set simulation...

Hi Ackbach, This looks good, I think you are moving in the right direction! I have found a pictue online that should clarify my intention. [FONT=Calibri]From the picture that we can use as an example. [FONT=Times New Roman] There are approximately 22 nodes circumferentially and 9 nodes...

I created a jpeg of size 145KB which is under 195KB for a jpeg but it still won't load up. 1) It is 7 nodes long 2) Distributing the force circumferentially over 7 nodes and axially over 7 nodes thereby giving total number of 49 nodes 3)Axis is z, correct 4)The total force is acting upwards...
