ICR-s of a 4 bar mechanism

Observe the determination of the ICR (Instan Centers of Rotation) of a 4 bar mechanism

- Move the ICR I23 and observe how the position of the ICR points I24 and I13 changes - The green ICR points I12, I23, I34 and I14 are the first ICR to being found - Then linking the ICR points I12 and I23 and linking the ICR I14 and I34 you can find the ICR I13 - In the same way, linking the ICR l12 and I14 and linking the ICR points I23 and I34   you can find the ICR I24
