Question

Ra tr 2. Using the Castigliano method again and compute the shear and the bending deformation along the original beam, then calculate the ratio of the shear deformation to the total deformation due to both bending and the shear (as a function of x). Hint - a proxy load needs to be added along the beam, say at x from A. The shear and moment diagrams due to this proxy load are below: a. m1 The shear area of a section (As) equal to A / K, where K theoretically equal to (A/IA2 (Q2 / t?) dA), and it could be estimated as (A / Aw). Therefore, for a wide flange I section, it is simply the area of the web (Aw). b. c. In the end, let P 0 to get the result (after integration).
