At a certain point in a structural member, there are perpendicular stresses 80 N/mm2 and 20 N/mm2, both tensile. What is the equivalent stress in simple tension, according to the maximum principal strain theory ? (Poisson's ratio = 0.25)
-
Duration along the critical path defines which of the following ?
1. Shortest duration needed
2. Shortest duration permissible
3. Longest duration needed
4. Longest duration permissible
Select the correct answer using the code given below : -
A cantilever of constant depth carries a uniformly distributed load on the whole span. To make the maximum stress at all sections the same, the breadth of the section at a distance x from the free end should be proportional to
