Unformatted text preview: Know the velocity vectors Position vectors must be perpendicular to velocity vectors Find ICR at intersection r B / ICR ICR is not stationary ICR 3 Where is the ICR? ICR Where is the ICR? ICR Resolve previous example ICR 5 5 = 45 Resolve previous example ICR = 45 True or False ICR for link BC is shown in the correct position? Cant use the relative velocity ICR not useful for open links v C = v B + BC r C / B 4 True or False The ICR is shown in the correct position? True or False ICR The ICR is shown in the correct position? Take Home Points For 2D rigid body motion, there always exists and Instantaneous Center of Rotation (ICR) that has zero velocity The ICR may be outside of the rigid body The ICR will change location over time...
