Homework Statement
Determine the tension cable A and B and the x , y , z reaction of the ball and socket joint at C .
Homework Equations
The Attempt at a Solution
I let the reaction of ball and socket joint at C = Fx , Fy and Fz
Sum of force in z direction :
TA +TB +FZ= 400
Sum of force in x direction :
Fx = 0
Sum of force in y direction :
Fy = 0
Sum of moment about X :
3TB 1.3(400) = 0
3TB+1.6FZ= 520
Sum of moment about Y :
2TA2TB = 1.5(400)[/B]
2TA+2TB= 600
Sum of moment about z :
1.6Fx = 0 , Fx = 0
Since TA +TB= 300 , so i sub this eq into TA +TB +FZ= 400 ,
i gt 300+Fz = 400 , Fz = 700N
3TB +1.6(700) =520 , TB =200N
TA 200+700=400 , TA = 100N
since the question mention the A, B is in tension , but i gt my TB and TA in negative value , i am wondering my ans is correct or not
