Question 1
Given a cuboid with σ₁₁ = 10 MPa, σ₂₂ = -5 MPa, τ₁₂ = 3 MPa, calculate the resultant stress vector on one of its faces.
💡 Hint: Break it down into components for calculations.
Question 2
A new material has an initial stress tensor of σ = [[5, 2], [2, 3]] in an arbitrary orientation. If it rotates by 45 degrees, how do the stress components transform?
💡 Hint: Think about using trigonometric identities to analyze the transformations.
