This lecture covers the systematic kinematic analysis of flexure-joints, including leaf springs, corner-blades, rod springs, and bellows. It explains the line of action, degrees of freedom, and hyperstaticity of various flexure-joint configurations. The instructor presents examples of parallel spring stages and flexure-bearings with intuitive methods. The lecture also discusses the arrangement of flexure-joints in parallel topography and orthogonally to each other, emphasizing the importance of checking degrees of freedom and ground indices.
