Question

Find all internal forces 

The image depicts a structural diagram of a truss subjected to various forces. Below is a detailed explanation of the diagram: 1. **Truss Structure**: The diagram shows a triangular truss supported at the left side by a pin support and at the right side by a roller support. The truss structure is symmetric with a base length split into two equal parts of 30 feet each. 2. **Supports**: - **Pin Support (Left)**: Located at the bottom left corner, this support is fixed in position but allows rotation. It is depicted by a solid circle with a line through it. - **Roller Support (Right)**: Located at the bottom right corner, this support allows for both rotation and horizontal movement. It is depicted by a circle on top of a small roller. 3. **Forces**: - **60 k**: There is a 60 kilopound (k) vertical force applied downwards at the top joint of the truss. - **30 k**: A horizontal force of 30 kilopound (k) is applied to the top right side of the truss. - **40 k**: There is a 40 kilopound (k) vertical force applied downwards at the midpoint of the truss base. 4. **Dimensions**: - The horizontal base of the truss measures 60 feet in total, split into two segments of 30 feet each. - The vertical height from the base to the top joint where the 60 k force is applied is 20 feet. This structural diagram is typically used in engineering studies to analyze the internal forces and moments in the members of the truss under the given loads.
