Transcribed Image Text: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
