3. The rectangular beam 'A ' has length l, width b and depth d. Another beam 'B' has the same width and depth but length is double that of 'A'. The elastic strength of beam 'B' will be __________ as compared to beam A.
6. According to Euler's column theory, the crippling load of a column is given by p = ?2EI/Cl2 In this equation, the value of C for a column with both ends hinged, is
7. A simply supported beam with a gradually varying load from zero at B and w per unit length at A is shown in the below figure. The shear force at B is equal to
10. The length of a conical bar is l, diameter of base is d and weight per unit volume is w. It is fixea at its upper end and hanging freely. The elongation of the bar under the action of its own weight will be
