In the structure shown, member ABCD is supported by a pin at C and a cable that wraps around pulley E, which is frictionless.
(a) Specify if member ABCD has complete fixity or partial fixity and whether it is statically determinate or statically indeterminate.
(b) Draw the FBD for member ABCD, and determine the cable tension in terms of force F and length L. Comment on any difficulties that might arise in your analysis.
