Ax =? and Ay = ?

Bx = ? and By = ?

The image depicts a structural truss system labeled as Figure P6.5. It includes a combination of horizontal and diagonal members forming a triangular framework. 

- **Points and Members**: 
  - The truss consists of nodes labeled A, B, C, and D connected by beams.
  - Members AB, AC, AD, and CD are diagonal beams, while BC and BD are horizontal.
  
- **Dimensions**:
  - The vertical height from point B to point A is given as 5 feet.
  - The horizontal distance between points B to C and C to D is 10 feet each.

- **Forces**:
  - Two downward forces of 10 kips each are acting at points C and D.
  
This truss setup is commonly analyzed in structural engineering to understand force distribution and to ensure stability and strength of structures.

Expert Solution
Step 1

Given data:

  • Load acting vertically downward at point C, PC = 10 kips.
  • Load acting vertically downward at point D, PD = 10 kips.

Draw the free-body diagram of the system,

Mechanical Engineering homework question answer, step 1, image 1

Since point B is supported by roller support, so the vertical reaction By is zero.

Therefore, the vertical reaction force at point B is By = 0 kips.

Apply equilibrium equation of forces in the horizontal x-direction,
