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\} \\

Hi All,
I am looking to determine how these Vases where modeled using maths on this webpage https://www.3dforprint.com/3dmodel/sine-wave-vase-generator/2116. It looks like the surface is parametrically defined and wrapped around a cylinder.
Interestingly he mentions
"Sine waves combine to...
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...

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

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...
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. From the picture that we can use as an example.
There are approximately 22 nodes circumferentially and 9 nodes axially giving a total of 198 nodes to...
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...
