The plate rotates about the rod joining A and B with a constant angular velocity of 33 rad/s. Knowing that, at the instant considered, the velocity of Point C is directed to the right, match: 1. (4.8, 4.43077, 1.84615) Angular velocity of rod. 2. (3.96, 3.65538, 1.52308) acceleration of point E 3. (0., -12.6923, 30.4615) velocity of point E 4. (-130.68, 120.628, 50.2615)
