Question
What is the reaction at force joint A and I. What is the C and T, the X and Y components, the load and the length of each member. Also could you put the answer like it is on the image.
Transcribed Image Text:**Diagram Description**
- The diagram illustrates a truss structure with labeled joints and members.
- The structure is symmetrical horizontally and has a total span of 12.00 units across the top.
- The points A to J are marked, with angles at joints B (45°) and D (70°) on the left side as well as angles at joints D (36.62°) on the right side.
- Vertical loads are applied at point C (20 lbs downward) and point E (30 lbs downward).
- There is a horizontal distance of 3.02 units from joint G to joint I.
- Reaction forces are indicated at joint A (vertically upward) and joint I (vertically upward).
