The crane's telescopic boom rotates with the angular velocity w = 0.06 rad/s and
angular acceleration a = 0.07 rad/s². At the same instant, the boom is extending
with a constant speed of 0.8 ft/s, measured relative to the boom. Determine the
magnitude of the acceleration of point B at this instant.
The motion of peg P is constrained by the lemniscate curved
slot in OB and by the slotted arm OA. (Figure 1)
If OA rotates counterclockwise with a constant angular velocity of 0 = 3 rad/s, determine the magnitude of the velocity of peg P at 0 = 30°.
Express your answer to three significant figures and include the appropriate units.
