Torque question need help!
Find the mass of the bar.

(My paint drawing sucks.)
A = 0.5 kg
B = 0.5 kg
L = 50cm
Angle = 76 degrees
[tex] fd_\perp [/tex] , Tcl = Tcc [tex] T_cl = T_cc [/tex] (Torque clockwise = Torque counter-clockwise)
Tcl = Tcc
m(9.8)(0.25 sin 76) = (0.5sin76)(9.8)
I have attemped the above, and ended up with mass = 1.49 kg which is impossible... (it was a plastic ruler).
I don't think I am missing anything given.
