$$ R_2+R_3-R4-R0=0 $$ |
Theta for the ground link will be assumed 0 for all t, and theta for R2 will be considered as the input link. Measuring from the rocke
r chair in real life, theta_2 varies from 165 to 15 degrees, with 165 as the closed position, and 15 as the open position.
The velocity loop equation is the time derivative of the vector loop, given by:
