An inverted T-section is being used as a lintel. The dimensions of the section are shown in Figure 2.3A. It is acting as a two-span continuous beam with a uniformly distributed action applied along both spans as shown in Figure 2.3B. The bending moments have been determined for a UDL of 1 kN/m, and are shown in Figure 2.3B. The centroid (𝑦𝑦�) is located 70.0 mm from the base of the section. Ix has been calculated to be 34.2*106 mm4. Iy has been calculated to be 13.0*106 mm4.

The question describes an inverted T-section used as a lintel, acting as a two-span continuous beam with a uniformly distributed load (UDL). Here's a breakdown of the key information provided:

1. **Inverted T-Section Geometry**: 
   - The section's centroid is located 70.0 mm from the base.
   - The moment of inertia about the x-axis (\(I_x\)) is \(34.2 \times 10^6 \, \text{mm}^4\).
   - The moment of inertia about the y-axis (\(I_y\)) is \(13.0 \times 10^6 \, \text{mm}^4\).

2. **Loading Condition**:
   - The beam is subjected to a uniformly distributed load of \(1 \, \text{kN/m}\) on both spans.
   - Bending moments due to this UDL have been calculated and shown in Figure 2.3B.

3. **Tasks**:
   a) **Determine the maximum tensile stress and the highest compressive stress** in the section due to the bending moments.
   b) **Determine the deflection** at the midpoint of each span.
   c) **Evaluate the stability against buckling** if the lintel is subjected to axial compression.

Given this information, do you want to proceed with specific calculations for tensile/compressive stress, deflection, or buckling analysis? Or would you like a detailed explanation of any particular concept? 

Let me know how you'd like to proceed!
