Define basic linkage mechanisms and its components
Links: Rigid elements that connect various parts of the mechanism.
Joints: Points where links meet and allow relative motion between them.
Actuators: Components that provide the driving force or motion to the mechanism.
Connecting rods: Links specifically designed to transmit force or motion between other links.
Pivots: Points around which links rotate or pivot.
Supports: Fixed points or structures that provide stability to the mechanism.
Constraints: Limitations on the motion or position of certain components within the mechanism.
1. Transmit motion
2. Change direction of motion
3. Increase or decrease force
4. Improve mechanical advantage
5. Enhance precision and accuracy
Bar mechanisms: Also known as four-bar linkages, are fundamental mechanisms in mechanical engineering.
Four-Bar Mechanisms:
A four-bar mechanism consists of four rigid links connected by revolute joints.
Types:
1. Crank-Rocker Mechanism
2. Double Crank Mechanism
3. Double Rocker Mechanism
