An instantaneous configuration of a four-bar mechanism, whose plane is horizontal, is shown in the Figure below. At the given instant, the link 2 has an angular velocity of 8 rad/s in CCW and angular acceleration of 67 rad/s² in CCW. The links 4 has a mass center at G4, a mass of 8 kg, and a moment of inertia 0,2 kgm². The link 2 and link 3 have no mass. The second link length is 0,6 m and makes an angle of 0-42 degrees with the vertical line. 8 !!!!!** G C AB=CO OG4=CG4 AD=BC=0.7 m BE=EC An instantaneous configuration of a four-bar mechanism, whose plane is horizontal, is shown in the Figure below.
