Correct Answer: At the neutral axis of a beam, the bending stress is maximum.
7. 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 free, is
8. A simply supported beam 'A' of length l, breadth b and depth d carries a central load W. Another beam 'B' of the same dimensions carries a central load equal to 2 W. The deflection of beam 'B' will be __________ as that of beam 'A'.
