- Problem #1 (Beam optimization). Calculate the length "a" of AB such that the bending moment diagram is optimized (the absolute value of the max and the min is at its lowest). Then draw the shear and moment diagram for the optimized length. Optimize the length to the nearest 0.1 m. You can use RISA 2D as a tool to find the optimized length, however you need to solve for the support reactions at A, B and C by hand and draw the shear and moment diagram by hand. w=20 kN/m A + + a 12 m B Carrow_forward2.
