Find the instantaneous linear velocity of C Find a point on your paper to draw the velocity polygon and scale the magnitude of the computed linear velocity Use the relative velocity equation for finding the linear velocity of D; Vp = Vc + Vp/c Remember that although the magnitudes are unknown, their directions can be identified Obtain the magnitudes of the unknown velocities from the velocity polygon For Link DE, repeat the process by using VẸ = Vp + VE ID. Add the vector VE/D to the head of p and extend the line as much as needed
