Q.7 A bead of mass m slide with speed u around a horizontal hoop of radius R. What are the constraint force equations? Q.8 Let the horizontal plane be the xy-plane. A bead of mass m slides with speed v along a curve described by the function y f(x). What are the constraint equations for the motion of bead?
