  2. What makes the factors that make the sketch clear: There is a close up of each mechanism in each pictures.

    Unclear: For the first sketch, there is no indication that the cam is the wheel or if it is fixed on the wheel. For both sketches, there is no explanation on what will happen when we fold up the table.
