Problem 2. Considering a 20 kg bar as shown in the figure: a) find angle theta and the reactions to keep the bar in equilibrium neglecting friction at both walls. b) If there was a couple located at the center of the bar and no friction at the walls with the angle theta found at a), find the couple if possible. c) If the angle of the right wall was 90° with the horizontal, and Theta was the same as obtained at a), what would be the force of friction (if any) at B in order to keep the body in equilibrium?
