A uniform slender rod of total length 800 mm and mass 5 kg is pinned at O (200 mm from one end) and is initially held by a cable at its other end at A as shown, such that the rod is at a angle of 30 with respect to the horizontal. Determine after the cable is cut A. the angular acceleration (magnitude and direction - for the direction, it is sufficient to indicate clockwise or counter- clockwise) of the rod as a function of the angle measured from the initial position of the rod, "1 200 mm 600 mm 30 B. the reaction (magnitude and direction relative to a standard reference) at the pin O when the rod becomes horizontal, and C. the reaction (magnitude and direction relative to a standard reference) at the pin O when the rod becomes vertical.
