- An object is moving between two points on a circle with radius R. The object can only move along the circle. The function F is the path length travelled between two points on the circle. a. Assume that the position of the object along the circle is described by an angle θ with respect to the center of the circle and the x-axis. Is this angle a minimum set of generalized coordinates for this problem? b. Assume that the position of the object along the circle is described by two Cartesian coordinates x and y, where the origin of the coordinate system is the center of the circle. Are these coordinates a minimum set of generalized coordinates for this problem? c. What would be the holonomic constraint for the two Cartesian coordinates x and y for the motion around the circle? d. What would be the Euler equation for this problem in Cartesian coordinates with holonomic constraint and Lagrange multiplier λ.b) In your own words describe first moment of area for any shape and its importance.
