👉 Isohyets, also known as isohysteresis or isostatic deflection, refers to a phenomenon in which an object undergoes a change in shape under a force that causes it to deform without changing its properties. This deformation can be due to external forces such as gravity, friction, or the interaction between two materials. In isohyets, the original shape of an object remains unchanged even after the applied force changes its direction. The concept arises from the idea of maintaining
