Spent all day today and yesterday trying to debug geometry calculations for the backhoe. Gave up and used conservative approximations for estimating the forces on the bucket tip and the moment the first actuator would have to exert. Posting weight calculations as well for the boom, stick, links, and bucket. Sketch: [1] Weight: [2] General calculations: [3]
