Referring to diagram below, the 2.4m, 3.6kN rod is held by a ball-and-socket joint at C(ie there is no moment existing at C) by two cables AD and AE (a) Express AD and AE in vector format, (b) D...
4. The space truss shown below is supported by ball and socket joints at C, D and E. The external force acting at joint A is F 10i+60j + 20k kN. Find forces in members AB, AC and AD. Indicate whether the axial forces in these members are compressive or tensile. Use method of joints. E (0,0.8,0) m 0.4 m 0.6 m
