  • Keith's copy of Introduction to Stresses

    by Keith Tarnowski and 1 other

    These practice questions cover:

    • resolving axial forces in a truss structure
    • stress & strain in a closed thin-walled pressure vessel (an example of 2D plane stress)
    • use of Mohr's circle for determining principal stresses for a 2D plane stress case
    • calculation of invariants for general 3D stress case, leading to von Mises stress and principal stresses
