Misc. Home project - rotary table calculations

AI Thread Summary
A mechanical engineering student is designing a motorized rotating table and seeks assistance with calculations related to its structural integrity. Key concerns include determining the minimum thickness of the aluminum table to prevent yielding under load, calculating strain, and ensuring the supporting pipe's dimensions can handle the weight without failure. The discussion references specific formulas from Roark's engineering handbook to assess stress and deflection, emphasizing that the design is governed by deflection rather than stress. Contributors provide detailed calculations and clarify parameters, leading to a better understanding of the mechanics involved. The student expresses gratitude for the guidance received, indicating progress in their project.

Correction to the P1 formula I gave you in post 21:

Create a new variable, m2 = table top sector self mass = M_table*[theta0/(2*pi)]. Change P1 formula to, P1 = -(pi/theta0)[(m1 + m2)*g]/(4 legs).

Correction to post 50: Change D0 in post 50 to D_profile.

Thanks, i already included the self mass of a sector in P calculations
