CONFIDENTIAL Q2 Figure Q2 shows a pendulum rigid body, the pendulum consists of a uniform plate with mass X kg and also slender rod of mass Y kg. Determine the horizontal, O, and vertical, Oy, component of reaction at pin O at this instant if the angular velocity, , of this pendulum rigid body is 3 rad/s, the moment inertia of rod, Id=m³, the moment inertia of plate, I plate (a² + b²). 1 12 X and Y are the last two non-zero digit of your matric number. For example, if your matric number is AN201050, X = 1 kg and Y = 5 kg. Hint: The pendulum is horizontal at this instant. Thus, the normal component of the rotating rigid body=x-direction and the tangential component=y-direction. (a) BNJ 20103 & BNT 20103 (b) (c) (d) Draw the free body diagram and kinetic diagram. Calculate the total mass moment of inertia, Il (2 marks) (4 marks) Calculate Oxby solving the Equation of Motion (E.O.M) for the forces in the x-direction. (3 marks) - END OF QUESTIONS - Calculate Oy by solving the Equation of Motion (E.O.M) for the forces in the y-direction and Equation of Motion (E.O.M) for the moment about point O. (6 marks)
