Gear A is held fixed, and arm DE rotates clockwise with an angular velocity of WDE = 6 rad/s and an angular acceleration of aDE = 3.4 rad/s. (Figure 1) Figure Part A A 0.3 m B 30% E 0.2 m > 1 of 1 > Determine the angular acceleration of gear B at the instant shown. Assume the counterclockwise rotation as positive. Express your answer to three significant figures and include the appropriate units.
