Homework Statement
The weight of rod AB is 4[N] and that of piece D is 10[N]. the moment at joint C is 1.8[Nxm]. what is the weight of rod AC.
Homework Equations
Moments: ##M=F\cdot L##
The Attempt at a Solution
Rod AB doesn't contribute to the moment at C:
$$10\cdot 15+180=W_AC\cdot 5\rightarrow W_AC=66[N]$$
It's 6[N] in the book.
