2.50 Two slender links, AC and BC, extend from a wall and support a pulley at C. A cable, tied at D, passes over the small pulley at C and experience an 80-lb force at its free end E. If the pulley is frictionless and of negligible determine the forces developed in members AC and BC. An inextensible (cannot stretch) cable AC and spring CB are originally horizontal. A 100-N weight is attached to point C, and the system is...
