Using the method of superposition, determine the magnitude of Mo in terms of the distributed load w and dimension a so that the deflection at the center of the beam is zero. El is constant. Mo W a Mo

Which of the beam cross-sections shown below would you use if you wanted to design a beam that deflected the least vertically due to a downward load? Assume that each of the cross-sections has the same total area. A B Cross-section A Cross-section B Cross-section C Cross-section D I + с D

Hi please present the solution clearly (preferabely on paper) with all steps so it is easier to understand since I have asked this question multiple times and I still don't get it. Thank you!

Point D is the fixed end of the cantilever beam shown in the figure and point A is its free end. Determine the vertical deflection at point C due to the applied concentrated load shown in the figure using Castigliano's theorem. Use [EI = 10^6 Nm ]
