How many links? LINKAGE EXAMPLES

Representing linkage systems with kinematic diagrams Step 1: Identify the frame. Step 2: Identify all other links. Step 3: Identify the joints. Step 4: Identify any points of interest. Step 5: Draw the kinematic diagram. LINKAGE EXAMPLES

STEP 1: IDENTIFY THE FRAME.

No links are grounded here, so the choice of frame is arbitrary. We could, for example, identify the top handle as the frame (1). 1 STEP 1: IDENTIFY THE FRAME.

STEP 2: IDENTIFY ALL OTHER LINKS.

The remaining moving parts are the bottom handle (2), the bottom jaw (3), and the bar that connects the top and bottom handles (4). 1 4 3 2 STEP 2: IDENTIFY ALL OTHER LINKS.
