PROBLEM 6.39*
The truss shown consists of nine members and is supported by a
ball and socket at B, a short link at C, and two short links at D.
(a) Check that this truss is a simple truss, that it is completely
constrained, and that the reactions at its supports are statically
determinate. (b) Determine the force in each member for
P (1200 N)j and Q 0.
