Question

The forces p and q of magnitude 1500 lbs and 1700 lbs respectively applied to the aircraft connection as shown. Knowing that the connection is equilibrium. Determine the tension s and t

Answer 1

By equilibrium of forces:

$$P+Q\cos40°=F_A\sin50°,\\ Q\sin40°=F_B+F_A\cos50°.\\\space\\ F_A=3658\text{ N},\\ F_B=-1259\text{ N}.$$
