    LaTeX LaTeX is not working for this code when I Preview

    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.

    LaTeX LaTeX is not working for this code when I Preview

    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...

    I Surfaces wrapped around a cylinder for 3d printing

    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...

    I Muons Decaying on Mt Washington: Expert Answers

    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...

    Angular Momentum of Glass on a String

    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...

    To stop a moving object -- Momentum or Kinetic Energy

    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...

    To stop a moving object -- Momentum or Kinetic Energy

    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...

    Automotive Why Does MSC Adams Show Increasing Acceleration with Constant Torque?

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

    Automotive Why Does MSC Adams Show Increasing Acceleration with Constant Torque?

    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...

    MHB Equation for a distributiong force on a half cylinder

    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...

    MHB Equation for a distributiong force on a half cylinder

    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...
