Force closure, form closure, and material closure are concepts in mechanical engineering related to the stability and equilibrium of a system. Force closure refers to the condition where external forces alone are sufficient to maintain the stability of a system. Form closure occurs when the geometric shape of the components provides stability without the need for external forces. Material closure involves the use of friction or other material properties to maintain stability within a system. These concepts are important in designing structures and mechanisms to ensure their stability and functionality. **
