Lecture 17: Numerical Problems on Degrees of Freedom of Mechanisms having Redundant/Idle DOF Link

If a link can be moved without producing any movement in the remaining links of the mechanism, the link is said to have a redundant degree of freedom. Such mechanisms expose the inconsistencies/limitations of Gruebler's equation. In this video, numerical problems (frequently asked university questions) on the determination of degrees of freedom (DOF), also known as mobility, of planar mechanisms having redundant links are solved with the step-by-step build-up of topics. 00:00 Concept of Redundant DOF 02:06 Solution to Problem 1 04:53 Solution to Problem 2 ---------------------------------------------------------------------------------------------------------------------------------------------------------------LECTURE VIDEOS ON KINEMATICS OF MACHINES Lecture 1: Scope of Kinematics of Machines: ttps://   • Lecture 1: Scope of Kinematics of Mac...   Lecture 2: Introduction to Kinematics of Machines | Overview of Kinematics of Machines:    • Lecture 2: Introduction to Kinematics...   Lecture 3: Difference between Machines & Mechanisms| Doodly Explainer Video:    • Lecture 3: Difference between Machine...   Lecture 4: Fundamental Concepts: Kinematic Links and their Types:    • Lecture 4: Kinematic Links and their ...   Lecture 5: Kinematic Pairs and their Types | Doodly Explainer Video:    • Lecture 5: Kinematic Pairs and their ...   Lecture 6: Kinematic Joints and their Types | Doodly Explainer Video:    • Lecture 6: Kinematic Joints and their...   Lecture 7: Kinematic Chains and their Types | Doodly Explainer Video:    • Lecture 7: Kinematic Chains and their...   Lecture 8: Mechanisms and their Types | Doodly Explainer Video:    • Lecture 8: Mechanisms and their Types...   Lecture 9: Kinematic Diagrams & their Construction | Doodly Explainer Video:    • Lecture 9: Kinematic Diagrams & their...   Lecture 10: Grashoff's Law & Inversions of Grashoff's Chain | Doodly Explainer Video:    • Lecture 10: Grashoff's Law & Inversio...   Lecture 11: Numerical Problems using Grashoff's Law | Identify Nature of Mechanism:    • Lecture 11: Numerical Problems using ...   Lecture 12: Inversions & Applications of Four-bar Chain | Animations:    • Lecture 12: Inversions & Applications...   Lecture 13: Mechanical Advantage & Transmission Angle of Four-Bar Mechanism | Toggle Positions:    • Lecture 13: Mechanical Advantage & Tr...   Lecture 14: Numerical Problems on Transmission Angle of Four-Bar Mechanism | Toggle Positions:    • Lecture 14: Numerical Problems on Tra...   Lecture 15: Understanding Degrees of Freedom & Mobility of Mechanisms | Kutzback Criterion:    • Lecture 15: Understanding Degrees of ...   Lecture 16: 10 Numerical Problems on Degrees of Freedom/Mobility of Planar Mechanisms:    • Lecture 16: 10 Numerical Problems on ...   --------------------------------------------------------------------------------------------------------------------------------------------------------------- LECTURE VIDEOS ON DYNAMICS OF MACHINES Playlist Link:    • Dynamic Force Analysis   --------------------------------------------------------------------------------------------------------------------------------------------------------------- DOODLY EXPLAINER VIDEOS Playlist Link:    • Doodly Explainer Videos   --------------------------------------------------------------------------------------------------------------------------------------------------------------- CAREER GUIDANCE Playlist Link:    • Career Guidance   --------------------------------------------------------------------------------------------------------------------------------------------------------------- Dr. V.
