Spring 2011 Due on February 8, 2011 ENME361: Assignment No. 1 1.4 Show that the acceleration of the particle in the rotating frame of Example 1.3 is 2 2 1 2 ( 2 ) ( 2 ) p p p p p p p p x y x y y x y x ω α = - - - + + - + a e e where is the magnitude of the angular acceleration of the rotating frame about the z axis. 1.5. In Figure E1.5, a slider of mass M r is located on a bar whose angular displacement in the plane is described by the coordinate θ . The motion of the slider from the pivot point is measured by the coordinate r 1 . The acceleration due to gravity acts in a direction normal to the plane of motion. Assume that the point
