Static Particle Wall: Cable Tension Forces and Components

[Apprentice123]

1) A section of wall of concrete pre-fabricated and temporarily, insured by the cables shown. If the tension in cable AB is 700 kgf, calls for determining the components of force and value of \theta y

2)
The tension in cable AB is 700 kgf and the cable BC is 900 kgf. Determine the components of the resultant of forces exerted by the cables in B.

Hi Apprentice123!

You'll need to balance the x y and z components separately.

Show us what you've tried, and where you're stuck, and then we'll know how to help!
