WebbFOUR BAR MECHANISM SUBMITTED BY: Neeruganti Ranjith Kumar ROLL NO. :19ME63R. Under the Guidance of Prof. Sanjay Gupta. DEPARTMENT OF MECHANICAL ENGINEERING. Four bar mechanism: - A simplest movable closed linkage with Four revolute joints, connecting four bars is commonly referred to as four-bar mechanism or four-bar linkage. WebbA four-bar linkage or simply a 4-bar or four-bar is the simplest movable linkage. It consists of four rigid bodies (called bars or links), each attached to two others by single joints or pivots to form a closed loop. Four-bars are simple mechanisms common in mechanical engineering machine design and fall under the study of kinematics.
