At the instant shown, the uniform slender rod with mass m = 35 kg is pin-supported at point O. It is subjected to a counterclockwise moment M = 66 N•m, has a counterclockwise angular velocity of W= 5.1 rad/s, and the dimensions a = 0.19 m and b = 0.58 m. Determine angular acceleration of the rod (in rad/s2) at this instant. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. Negative sign must be included if the angular acceleration is clockwise. Take g = 9.81 m/s2. O. · M Your Answer: Answer
