The aim of this Kinematics Based on Four Bar Linkage BE Mechanical Seminar Topic & Project Report is to make a four bar linkage and display the movement by a hand crank. Based on rubric with five other legs, there is no need to turn, efficient and display analysis and calculations of the outermost point of linkage.

The four-bar linkage is a movable and simplest linkage. It includes four rigid bodies known as bars or links. These are connected by pivots to produce a closed loop. Four-bars are the common mechanisms in mechanical engineering and kinematics. The pivot joint includes one rotational degree of freedom and mechanism is planar.

The planar four-bar linkages include many different motions based on calculations. Many mechanisms include movable members and these motions form trajectories points on the mechanism. The link is rigid in every mechanism which acts like a frame.

Inversions mechanisms are configurations with manipulation of the rigid link known as frame. The data from one link is utilized to know about other inversions. Inversion technique is used for mechanisms synthesis and analysis.

There are two kinds of joints based on contact type. They are lower pair joint and higher pair joint. Lower pair joint is contact of area among two mating surfaces whereas higher pair joint is link among mating surfaces like line contact.

Conclusion:

The Kinematics Based on Four Bar Linkage BE Mechanical Seminar Topic & Project Report concludes that the constant body is known as ground link which is required to get every position. There are two links linked to the ground are known as grounded links and the left link is known as coupler link. The second grounded link is the follower link.
