I would like to design a model like the one in the attached figure.(1) is initial state, (2) is after deformation．
・The yellow block is the axis.
・The gray blocks are fixed to the blue and green blocks.
・The gray block is a strip of elastic material.
・The distance between the blue and green blocks is constant.
・Rotate the blue block to change the gray elastic.
I would appreciate it if you could attach the model you created.
