The vertical plate shown is welded to arm EFG, and the entire unit rotates at the constant rate 1 ω = 1.6 rad/s about the Y axis. At the same time, a continuous link belt moves around the perimeter of the plate at a constant speed u = 90 mm/s. For the position shown, determine the acceleration of the link of the belt located
