According to Euler's column theory, the crippling load of a column is given by p = π2 EI/Cl2 In this equation, the value of C for a column with both ends hinged, is
-
The shear force at a certain point on a beam changes sign from +ve value to -ve value or vice versa. The bending moment at that point will be zero.
-
In a riveted joint, when the number of rivets decreases from the inner most row to outer most row, the joint is said to be
-
A spring, when loaded, is permanently distorted and recover its original shape when the load is removed.
-
When a rectangular beam is loaded longitudinally, the shear force develops on the top layer.
-
The capacity of a strained body for doing work on the removal of the straining force, is called
-
The given figure shows the Mohr's circle of stress for two unequal and like principal stresses (σx and σy) acting at a body across two mutually perpendicular planes. The tangential stress is given by
