R M 2 A Problem 7/36 7/36 The small motor M is pivoted about the x-axis through O and gives its shaft OA a constant speed p rad/s in the direction shown relative to its housing. The entire unit is then set into rotation about the vertical Z-axis at the constant angular velocity 2 rad/s. Simultane- ously, the motor pivots about the x-axis at the con- stant rate for an interval of motion. Determine the angular acceleration a of the shaft OA in terms of . Express your result in terms of the unit vectors for the rotating x-y-z axes. Answer (if it helps): 7/36 -Op sin i + (p cos - Nj p sin k R M 2 A Problem 7/36 7/36 The small motor M is pivoted about the x-axis through O and gives its shaft OA a constant speed p rad/s in the direction shown relative to its housing.
