Modeling of optimized flexible four bar mechanism considering joint clearances are developed at first. The dynamic analysis such as Moment, Torque, Energy and structural analysis such as Deformation, different mode of Stress are done by considering load in coupler point of optimized flexible four bar linkage. The deformation and stress are compared by considering different materials. Lagrange's equation is used to define the direction of the joint clearance. Differential evolution algorithm is used to optimize the length of links which reduce the gap between the desirable and actual path.
