Mechanism

1.Define basic linkage mechanisms and its components 

1. Links: Rigid elements that connect various parts of the mechanism.

2. Joints: Points where links meet and allow relative motion between them.

3. Actuators: Components that provide the driving force or motion to the mechanism.

4. Connecting rods: Links specifically designed to transmit force or motion between other links.

5. Pivots: Points around which links rotate or pivot.

6. Supports: Fixed points or structures that provide stability to the mechanism.

7. Constraints: Limitations on the motion or position of certain components within the mechanism.

Four bar mechanism:

• A four-bar mechanism consists of four rigid bars (links) connected by joints. It typically includes an input link (driven by a motor or manually), an output link (performing the desired task), a coupler link (transmitting motion between input and output), and a fixed link (providing stability). The arrangement of these links and joints allows the mechanism to perform various types of motion, such as rotation or translation, based on the input.
