Visualization of Relative Velocity in Plane Motion

 

 

Given:  The velocity of point A,  vA , rAC,  and  ω k.  Objective:   Draw vector diagram for  vC .

 

                                           

 

 

                                    

 

 

Note:  The velocity of C relative to A,  VC/A,  is perpendicular to the line from A to C (Fig 2A).

            It's what you see if you sit at A and look at C.  The direction comes from the sign of the

            angular velocity,  ω , (Fig 2B) and has a magnitude equal to the distance, AC, times the

            angular speed, ω  (Fig 2C)    Click here to proceed to the relative acceleration diagram.

 

Add vectors on RHS to obtain vector representation of  VC  on LHS.  Click here to continue
