Question

Transcribed Image Text:**Problem 2**
For the same two-span continuous beam in Problem 1, determine the moment at C if point C settles 1.5 inches downwards. Given \( E = 29000 \) ksi, \( I = 300 \) in\( ^4 \).

Transcribed Image Text:### Diagram Analysis
The image depicts a schematic of a horizontal beam with marked temperature changes and structural properties.
#### Beam Layout
- **Supports and Points:**
- Point A: A fixed support is located at the left end of the beam.
- Point B: A roller support on the right end at 60 inches above the base level.
- Point C: A marked point at the center of the beam.
- **Distances:**
- The total length of the beam is 40 feet, divided into two equal segments of 20 feet each between Points A and C, and Points C and B.
#### Temperature and Material Properties
- **Temperature:**
- \( T_1 = 200^\circ F \) at Point A.
- \( T_2 = 50^\circ F \) at Point C.
- **Material Properties:**
- Elastic Modulus \( E = 29000 \) ksi.
- Moment of Inertia \( I = 300 \) in\(^4\).
- Coefficient of Thermal Expansion \( \alpha = 6 \times 10^{-6} \) /°F.
This diagram likely represents a structural thermal analysis scenario, where temperature variations across the beam are analyzed in conjunction with its mechanical properties.
