Question 1

Given a system of equations derived from a real-world engineering scenario, determine the ranks of the relevant matrices and analyze the results to conclude if the system is consistent and the type of solutions.

💡 Hint: Utilize the relationships between rank and solutions we've discussed.

Question 2

In a project involving multiple constraints in structural design, assess how the rank of associated matrices affects potential designs. Suggest adjustments if the designs are determined to be indeterminate.

💡 Hint: Think about what additional constraints can improve design stability.
