Please help me solve this. Thank you

12' 12' 7 20 40' 40' 40 40' 40' 20 CABLE CONCRETE ( TOWER ) LOAD Fy = 290ksi Fallow = 4000 psi 10 kip/ foot E = 29000ks; E = 5000 ks; 1 = 1.5 = 1.5 For the above bridge, assume the deck is not connected to the tower or either bank of the river. The deck free floats above the ground and the mast. 1. (25 pts) Solve for the force in each cable by method of joints. (6 total) 2. (15 pts) Solve for the force in each deck segment. (7 total) 3. (15 pts) Solve for the force in each tower segment. (5 total) 4. (25 pts) Solve for the force in each cable by graphical method. 5. (5 pts) Did you get similar answers for questions 1 and 4? You should. 6. (15 pts) Calculate the required cable diameter. Round up to the nearest 1/8". 7. (extra credit 10 pts) The mast is to be square in section and made of concrete. What dimensions should the cross section have (the edge length. In inches.)? Use k=2
