Hello-
I am trying to determine the dynamics of this linearly-damped hinge. Assuming that:
∑Fx = -Fd * cos(45-θ/2) + Rx = m*dvx/dt
ΣFy = -Fd * sin(45-θ/2) - Fg + Ry = m*dvy/dt
ΣM (about the hinge) = Fg*cosθ - Fd*cos(45-θ/2)
I'm having trouble deriving the differential equations from these force balance equations. Do I need to form a continuity equation next? Any help is greatly appreciated!
Thanks...

I am trying to determine the dynamics of this linearly-damped hinge. Assuming that:
- v(0) = 0
- damping constant = b
- door has mass = m
∑Fx = -Fd * cos(45-θ/2) + Rx = m*dvx/dt
ΣFy = -Fd * sin(45-θ/2) - Fg + Ry = m*dvy/dt
ΣM (about the hinge) = Fg*cosθ - Fd*cos(45-θ/2)
