Question
Find the forces in members using method of joints

Transcribed Image Text:**Figure P5.11. Truss:**
This diagram depicts a truss with members and supports.
- The structure is labeled with points A through E.
- Vertical loads of 10 kips (k) are applied at points C, D, and E.
- The height of the truss above point A is 20 feet.
- The distances between points A to B, B to C, and C to D are all 12 feet with D to E being 14 feet.
- Vertical dimensions of each section are 6 feet, with individual segments of 4 feet.
**Figure P5.12. Truss:**
This figure shows another truss supported at points A and G.
- Points labeled include A, B, C, D, E, G, and H.
- Horizontal sections from A to D are 4 meters each.
- The height from A to C, C to D, and G to H is 3 meters.
- Vertical loads are applied: 40 kilonewtons (kN) at point E and 80 kN at point G.
**Figure P5.13 to P5.19 Trusses (Referenced in the Text):**
- These refer to other truss designs. The objective is to determine the forces in the members marked with an "X" using the method of sections.
- Loads are specified at 20 kips at the top nodes and 80 kips at the bottom nodes.
- The horizontal spans are divided into sections of 8 feet.
This setup is part of a section titled "5.6: Methods of Truss Analysis" from Engineering LibreTexts, instructing students on how to analyze forces within truss structures.
