3. ACCELERATION: A four-bar linkage is shown below. Find the magnitude and direction of a, and a. (B) (5 points) Find the magnitude and direction of the absolute acceleration ofpoint

E on link 3. RAD= 10 cm, RBp = 15 cm, RBc = 60 cm; RCE = 65 cm; RĘF = 15 cm(Note: ADB and FEC are right triangles.) w2 = 2 rad/s cw az = 1 rad/s? ccw A velocity analysis has already been completed. resulting in these values: W3 = 0.449 rad/s ccw Wa = 0.462 rad/s cw%D
