The attachment shows a structure. I'm supposed to calculate the forces in the members B and C. I try the following:

[tex]
\sum M _A = BL + 2CL - F \cdot {3 \over 2}L = 0
[/tex]

[tex]
\sum {F_Y = B + C - F = 0}
[/tex]

Solving for B and C from this doesn't yield the correct answer, which is B=3F/10 and C=6F/10.

Can someone explain?

Please post homework problems in the homework help section.

As for your problem, it looks as if point C is free floating. So there is no force developed at C. Hope that solves your worries.
