Question
  • Determine the force in each member of the truss shown. Each member is secured at its ends by a ball-and-socket joint (A, B and C ends, meaning no carrying moment capacity).
The image is a diagram of a truss structure designed for educational purposes. It illustrates a truss with two triangular sections. Here's a breakdown of the elements in the diagram:

1. **Triangle Sections:**
   - The left triangle has a base angle labeled as 30 degrees.
   - The right triangle has a base angle labeled as 60 degrees.

2. **Truss Geometry:**
   - The truss is symmetrical, with each half of the base measuring 50 feet, making the total length 100 feet.

3. **Load:**
   - A downward force of 2000 pounds-force (lbf) is applied at the top of the truss where the two triangles meet.

4. **Height:**
   - The maximum vertical height of the truss is 21.65 feet.

5. **Support:**
   - The structure shows two types of supports.
     - The left support is represented as a hinge or pivot (typically a triangle symbol).
     - The right support is shown as a roller (typically a circle symbol).

This diagram can be used to study the forces and moments in a truss structure, specifically analyzing the effects of load distribution and support reactions.
