a long concrete bearing wall has vertical expansion joints placed every 40 feet. Determine the required width of the gap in a joint if it is wide open at 32°F and just barely closed at 90°F. Use the thermal expansion coefficient /°F. The solution must include equations, procedures, final calculated width, and units ### Concrete Bearing Wall with Expansion Joints#### Diagram OverviewThe diagram illustrates a section of a concrete bearing wall incorporating expansion joints. The wall is segmented into equal sections, each measuring 40 feet in length. #### Detailed Description- **Concrete Bearing Wall**: This is the main structure shown in the diagram, providing support and stability. It is depicted as a long, rectangular block divided into segments.- **Expansion Joints**: Positioned between each 40-foot segment of the wall, these joints are crucial in accommodating temperature-induced expansion and contraction. This prevents cracks and structural damage over time.#### Important Points- **Segment Length**: Each segment of the concrete wall measures 40 feet, for a total of three segments shown.- **Purpose of Expansion Joints**: They allow for movement due to thermal expansion and contraction, ensuring the integrity of the structure.This design is essential in large concrete structures to maintain durability and prevent cracking.

we know width of each gap is 2l2=lWhere l=Lα∆Tα=6×10-6 per °F for concrete∆T=90-32=58°FL=40'
