Consider the frame on which two couples are acting, F1 = 32N at θ1= 35°,
F2= 85N at θ2 = 49°.
The resultant couple moment is zero.
Assume L1 = 0.30 m, L2 = 0.90 m, L3 = 1.37 m, and L4 = 0.54 m. Determine the distance d.

i got d=3.3283m
i resolved the forces and determined the componets which would provide torque
and i found this answer by equating all the torques on the system from the point b
first i determined the directions of all the torques and made an equation by taking te torques in the same direction on one side and the other torques on the other side
