In any beam when the moment of inertia about the neutral axis is doubled, its deflection is
The limits of percentage of the longitudinal reinforcement in a column is given by

In a simply supported beam AB with a concentrated load W at a distance 'a' from support A and 'b' from support B, the deflection under the load is
For the design of retaining walls the minimum factor of safety against over-turning is taken as
A cantilever beam is loaded by a point load at the free end. It is likely to fail by B.M.
