Started programming on a ZX spectrum in the 80's and have moved through Assembly, Turbo Pascal, C++, C#, Fortran. My main area of focus is engineering and scientific computing like numerical methods and 3D graphics.

comment Why isn't time axis vertical?
I do not understand the question? What curve are you talking about? The illustration has time as an independent quantity.

comment how to draw mechanical engineering problems
I sometimes draw with Asymptote Vector Graphics, but more often than not, with Power Point and its crappy sketching abilities. I also use IguanaTex to embed LaTeX into slides

comment how to draw mechanical engineering problems
+1 I agree there is huge hole out there for scientific/engineering sketches. Computer Aided Free Body Diagrams is non existent practically and as a programmer and an engineer I often think about trying to fill this void.

You know about lateral acceleration $a_L = \frac{v^2}{r}$?

comment Nature of tension in a massless rope
The force is a constraint. It is there to ensure the fixed length of the rope. It the rope was straight you would see it as equal and opposite forces (action/reaction), but the pulley transforms the direction.

comment Cutting a circle and moving endpoints
The end conditions should be that the force components on the top point should be equal and opposite of the force components on the bottom point. Otherwise the wire would move.

comment How can I measure the speed of a figure skater's spin?
Would high speed video do? Count the number of turns, convert to degrees and measure the time using the number of frames.
