Here it is, please explain each and every steps. thank you!

Find (Explain why this expression describe the tension in cable CD acting at C) The correct answer is (-0.96TCD i - 0.28 TCD k)lbs But why? Determine tension of cable CD *Answer is 625lb but please show steps determine magnitude of component of reaction force that hinge A exets on rod ABC in z-direction. Answer is 175lbs but why? Determine the magnitude of the component of reaction moment that hinge A exert on rod ABC in the Z-direction. *Its 2.91 ft.kip please show steps

Explanation / Answer

since you image is not clear i cannot find the exact position vector of points..

so i am telling u the concept to solve this question

for part 1

since it is in equillibrium make net torque about point O i.e origin 0

because it is equillibrium situation

so

get T in vector form whose unit vector is in direction of line CD

and there will be another torque due to force acting on the rod at its middle point.....

so equating torque to zero gives you

for part d

after getting value of T and F is known

you can make sum of all forces in z direction to be zero

so 3 forces will act in z direction

1 is F 2 is due to tensio and third is normal

so Nz+Tz+F=0

so this will give u Nz
