Question

The member OA of the industrial robot telescopes and pivots about the fixed axis at point A. At the instant shown, θ = 60.8° and ω = 1.2 rad/s. If α = 0.8 rad/s², OA = 0.9 m, and OA' = 0.5 m/s, determine the magnitudes of the velocity and acceleration of joint A of the robot. Also, sketch the velocity and acceleration of A and determine the angles which these vectors make with the positive x-axis. The base of the robot does not revolve about a vertical axis.
