The rigid L shaped bar is supported by a pin at O, is attached to a pulley at B and it rests on a wall at point A, as shown in the figure. The weight of the mass attached to the pulley is equal to m1 = 10 kg. The bar is subjected to the following external loads (directions as shown in the figure): Distributed load with w1 = 700 N/m and w2 = 300 N/m Couple moment at point O equal to MO = 5 N·m Calculate the support reactions. What is the weight required to cause loss of contact at point A?
