The cross-braces (labeled 1 and 2) in the truss are cables that can support only tension and not compression. They slip past each other where they cross; i. e. they are not pinned together there.
(a) Please indicate which of the two cross-braces is in tension (the other will be slack, with zero force), and calculate its tension.
(b) Now suppose that the cross-braces are replaced with regular rigid struts that can support both tension and compression. Would the structure now be statically determinate
