All the best! :-)

1. A 300 N load is attached to a small pulley which may roll freely on the cable ACB. The pulley and load are help in the position shown by a second cable DE which is parallel to the portion CB of the main cable. Determine (a) the tension in the cable ACB, (b) the tension in cable DE. Neglect the radius of the pulleys and the weight of the cables.

2. The couple aplied at C has an unknown magnitude M. Determine the range of values of M for which the line of action of the resultant of the system will intersect the bracket.

3. A 5 by 8 m sign of unifrom density weighs 2700 N and is supported by a ball and socket at A and by two cables. Determine the tension in each cable and the reaction at A.
