Begin the analysis by setting up a model. Consider a long, straight, rectangular plate and construct a free-body diagram (FBD). Model it as one long, continuous, rectangular plate that is attached at the root. Don't solve anything here. At this point, you want to include the boundary conditions, forces, torques, and internal reactions. Consider your knowledge of beams and torque tubes. I was hoping I could get help with designing this dimensionless model while getting help in understanding what each force was doing. Thank you!
