(Solved): Gear A rotates counterclockwise with a constant angular velocity of \omega _(A)=10ra(d)/(s), while ...
Gear A rotates counterclockwise with a constant angular
velocity of \omega _(A)=10ra(d)/(s), while arm DE rotates clockwise with
an angular velocity of \omega _(DE)=6ra(d)/(s) and an angular
acceleration of \alpha _(DE)=4.5ra(d)/(s^(2)). (Figure 1)
Part A
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.
\alpha _(B)=
