Homework Help: Rigid body kinematics

  1. Apr 23, 2010 #1
    sorry someone can help me with this problem about the revolutions of the plate??



    thanks!



    A small block B rotates with the horizontal plate A in Fig. the
    distance between the block and the axis of rotation is r = 100 mm, the
    angular acceleration of the plate is α = 2 rad/s2 = constant and
    the initial angular velocity is zero. calculate and graph.



    a)
    the magnitude of the acceleration AB block as a function of rotation
    angle θ for the first two revolutions of the plate.



    b)
    the φ angle formed by the acceleration of the block AB with OB radius
    as a function of rotation angle θ for the first two revolutions of
    the plate.
