Question
The member OA of the industrial robot telescopes
and pivots about the fixed axis at point 0. At
the instant shown, 0 = 60°, ô = 1.2 rad/s, ö =.0.8
rad/s2, OA = 0.9 m, OA= 0.5 m/s, and OA =
-6 m/s2. 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 posi-
tive x-axis. The base of the robot does not revolve
about a vertical axis.
