WebMar 29, 2024 · 5. Principal Stresses. Principal stresses act on planes where τ = 0. The larger principal stress is called the major principal stress, and the smaller principal stress is called the minor principal stress. Similar to finding transformed stresses, we draw lines from the pole to where τ = 0, or the two “x-intercepts” on the circle. WebJun 21, 2024 · The principal stresses at a point in an elastic material are 100 N/mm ² ( tensile) and 80 N/mm² ( tensile ). If the ultimate stress in simple tension is 200 N /mm ², determine whether the failure of material will occur …
