Chapter 20.4, Problem 39P
At the instant θ = 60°, the telescopic boom AB of the construction lift is rotating with a constant angular velocity about the z axis of ω1 = 0.5 rad/s and about the pin at A with a constant angular speed of ω2 = 0.25 rad/s. Simultaneously, the boom is extending with a velocity of 1.5 ft/ s, and it has an acceleration of 0 5 ft/ s2, both measured relative to the construction lift. Determine the velocity and acceleration of point B located at the end of the boom at this instant.
