Thank you. Is it possible to probe (find out) a moment reaction on a rotational joint (or any jont) where I applied rotational velocity in RBD? After you applied a "remote force", how could you calculate "the necessary design torque (reaction)" to balance the moment caused by remote force instead of applying two moments to two revolutionary joints in your 4 bar linkage in demonstration section of the video 27:53.? As I experienced from Ansys RBD, when a rotational joint is free to rotate, no torque reaction is induced about this free axis. Should I apply additional constrain its rotational axis where I will take torque reaction? But if I constrained the rotational DOF, how could I apply rotational velocity (or any load) to this constrained axis (DOF)? Is there any easy way or technics to probe torque requirement (reaction)?
