Let’s think together

“Science is the art of asking right questions instead of providing right answers”

Below are shared ongoing scientific questions which I am curious about. If you are also curious about some of these questions then we have a potential collaboration chance.

1. I have developed an innovative general method which can quickly within 15-20 seconds by using hands determine geometric instability of every structural frame. The method has several advantages compared to currently existing methods such as Kennedy’s Theorem, Method of Instant Center of Rotation or others. Below (attachments) are written paper drafts and are drawn eight examples (1-4, 5-8, geometrical lengths for all examples are either L or 2L) of complex structurally indeterminate systems and I am looking for potential collaborators who can explain if these systems are stable or unstable using currently known methods and who might be interested for collaboration to publish the new method together. As my background is not from theoretical structural mechanics, I am looking for experts who are willing to collaborate with me in advisory role.       Structural_Stability_draft_Josko        Structural_Stability_draft_appendix_Josko   How_to_Determine_Geometric_Stability_of_Complex_Structural_Frames?

2a. If airplanes have the most optimal altitude for long distance flying, do submarines similarly have the most optimal depth for long distance diving?

2b. Which is the formula to determine the most optimal (the fastest while spending the least amount of fuel) long distance flying Longitude/Latitude and altitude for airplanes? Is input only the wind speed or other parameters are important as well? Which-is-the-formula-to-determine-the-most-optimal-long-distance-flying-latitude-and-altitude-for airplanes?
