2. According to Euler's column theory, the crippling load of a column is given by p = ?2EI/Cl2. In the Euler's formula, the value of C for a column with one end fixed and the other end hinged, is 1/2.
6. The given figure shows the Mohr's circle of stress for two unequal and like principal stresses (?x and ?y) acting at a body across two mutually perpendicular planes. The tangential stress is given by
