** Question No : 9**

If f is the maximum allowable bending stress in a tension member whose radius of gyration is r and depth is 2y, the required cross sectional area A is given by

A = My/fr²

A = My²/fr²

A = My/fr

A = My/f²r²

** Question No : 10**

Modified moment of inertia of sections with a single web, is equal to moment of inertia of the section about Y-Y axis at the point of maximum bending moment and is multiplied by the ratio of
