2. 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'.
3. 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
Correct Answer: one end fixed and the other end free
7. Two bars of different materials and same size are subjected to the same tensile force. If the bars have unit elongation in the ratio of 2:5, then the ratio of modulus of elasticity of the two materials will be
9. 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 resultant stress is given by
10. When a body is subjected to bi-axial stress i.e. direct stresses (?x) and (?y) in two mutually perpendicular planes accompanied by a simple shear stress (?xy), then maximum shear stress is
