A wall-mounted jib crane consists of an I beam that is supported by a pin at point A and a cable at point C, where A and Clie in the xy plane. A crate at E is supported by a cable that is attached to a trolley at point B where the trolley may move along the length of the I beam. The forces supported by cables CD and BE are 4.5 kN and 2.5 kN, respectively. For the value of a = 40°, determine expressions for the forces the two cables apply to the I beam.
