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? Can’t use the relative velocity ICR not useful for “open links” v C = v B + ω 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...
