Actuated Pulley (without mass and inertia; geometric constraint)
Mechanics/Translational/Components
Actuated pulley without mass and inertia. The translational flange positions s = flange_a.s (right), s1 = flange_b1.s (top left) and s2 = flange_b2.s are constrained by the equation:
(L + s) = (s1 + s2)/2 .
The rotational flange axle (bottom) can be connected with a component of the Mechanics/Rotational/Components palette or a electric/mechanic transformer (see Electrical/Analog/Basic/EMF).
The relation between rotational torque axle.tau and translational forces is:
axle.tau / r = flange_b1.f - flange_b2.f .
Where r is the effective radius of the pulley.
