Let's break down the two figures from the image:

1. Moment of Inertia Calculation (I-section beam):

   • The first figure depicts an I-beam section with the following dimensions:
     • Top flange width = 200 mm
     • Bottom flange width = 200 mm
     • Flange thickness = 15 mm
     • Web height = 300 mm
     • Web thickness = 15 mm

   To compute the moment of inertia of this I-section about the x-axis (horizontal) and y-axis (vertical), we can use the parallel axis theorem and standard formulas for moments of inertia of composite shapes.

2. Given Beams:

   • The second part contains two beam diagrams:
     1. First Beam:
        • Simply supported beam with supports at A and B, having point loads of 15 kN spaced evenly across intervals of 4 feet.
     2. Second Beam:
        • Another simply supported beam with a distributed load of 10 kN/m over a 6-meter span from A to C, and a point load of 50 kN applied at B, located 2 meters from C.

Would you like to start with the moment of inertia calculation for the I-section, or would you prefer an analysis of the beam reactions and internal forces for one of the beam diagrams?

Feel free to ask for more details or any specific question you have! Here are five questions that might be relevant:

1. How do you compute the moment of inertia for a composite I-beam section?
2. What are the formulas for calculating the moment of inertia along the x-axis and y-axis?
3. How do we determine reactions for the simply supported beam with point loads?
4. How do we analyze shear force and bending moment diagrams for the second beam with both distributed and point loads?
5. What is the significance of calculating moments of inertia in structural analysis?

Tip: For composite sections like I-beams, using the parallel axis theorem is key to obtaining accurate moment of inertia values for non-centroidal axes.
