    Choosing Sides: Loyalists in Revolutionary America On April 30, 2014, Dr. Ruma Chopra spoke in the University Scholar Series hosted by Interim Provost Andy Feinstein at the Dr. Martin Luther King, Jr. Library. In this talk, Dr. Chopra discusses colonial resistance to the American Revolution. Dr. Chopra’s book, Choosing Sides: Loyalists in Revolutionary America, details arguments given by America’s original colonists, including slaves and Native Americans, against the formation of the United States. Even hundreds of years into America’s existence, these arguments are echoed and championed both within and beyond our borders. Dr. Chopra is an Associate Professor in the Department of History at SJSU.https://scholarworks.sjsu.edu/uss/1030/thumbnail.jp

    Dynamic stability of a bearingless circulation control rotor blade in hover

    The aeroelastic stability of flap bending, lead-lag bending and torsion of a bearingless circulation control rotor blade in hover is investigated using a finite element formulation based on Hamilton's principle. The flexbeam, the torque tube and the outboard blade are discretized into beam elements, each with fifteen nodal degrees of freedom. Quasisteady strip theory is used to evaluate the aerodynamic forces and the airfoil characteristics are represented either in the form of simple analytical expressions or in the form of data tables. A correlation study of analytical results with the experimental data is attempted for selected bearingless blade configurations with conventional airfoil characteristics
