👉 In physics, the term "flexure" refers to a phenomenon where a body or object changes its shape when subjected to an external force. This can be due to a change in material properties such as density, elasticity, or thermal expansion, or within a structure itself. For example, a beam under tension would experience flexure if it is stretched or compressed. This phenomenon occurs because the stress produced by the applied load is distributed over the entire length of the beam, leading to deformation at any point
