0.2 m * plate 0.3 m slender rod @=3 lad/s 0.5 m
Figure shows a pendulum rigid body, the pendulum consists of a uniform plate with mass 3 kg and also slender rod of mass 1 kg. Determine the horizontal, Ox and vertical, Oy, component of reaction at pin O at this instant if the angular velocity, o, of this pendulum rigid body is 3 rad/s, the moment inertia of rod, I rod = ml³, the moment inertia of plate, I plate=m 3 (a² + b²). 1 12 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) (b) Draw the free body diagram and kinetic diagram. Calculate the total mass moment of inertia, I total
