The two uniform 6-kg bars DC and EF are fixed (welded) together at E. At the instant with = 68°, bar BC has an angular velocity o = 2.7 rad/s and an angular acceleration a = 4.9 rad/s² as shown. (a) [30 pts] Determine the internal forces at E including the normal force Ne, shear force VE, and moment ME. (6) [5 pts ] How do you know if your answers are correct? State your reasoning or present an alternative method to solve the problem. (Hint: this may include ways such as unit checking, intuition, alternative methods, group discussion etc.) 2 m E D с 1.5 m 680 1.5 m a = 4.9 rad/s2 *w = 2.7 rad/s А B B
