That is a very broad question. When 20 pounds mass is in motion and you try to stop it, your going to have more than 20 pounds force exerted on the moment and at what distance from the pivot or fulcrum. Without more info about your application, I would suggest you try schedule 40 PVC, it's surprisingly strong, light and quite resilient. Also, an I-beam cross section is very efficient if the force is applied vertical and without any lateral stresses.
