Hello there!
I am a professional Mechanical Engineer MEng PhD with 10+ years in the design industry and more than 150 completed projects. Further, I have excellent command of English. Currently I teach in the University Engineering Design and Strength of Materials to BEng level Mechanical Engineers.
I can provide the analytical solution, this is a Castigliano's theorem problem. Also the FEA numerical solution in ANSYS and I will create the FEA macro parametric to achieve the 3rd objective too. I do not need any clarifications, I can start immediately when you award me the job.
Best regards
Antonis
