Physical Pendulum Program: Cylinder

I am programming a physical pendulum in which I need to animate an object, preferably a cylinder, to rotate back and forth on the pivot point which I have assigned to be 0. Does anyone know how I would be able to plot an oscillating cylinder, or even just a rectangle would be fine, from the pivot point? Right now I have just a square attached to a red line.

Inside the axes create a hggroup. Parent the drawing of the object to the hggroup. Then you can apply hgtransform to the hggroup to rotate or move the object
