QUESTION: 1

A simply supported beam of span L carries a point load Pat the mid span. The downward deflection under the load will be

Solution:
QUESTION: 2

A simply supported beam carries a concentrated load P at the mid span and experiences a maximum deflection Av Subsequently, the breadth and depth of beam is doubled. The corresponding deflection under the load will become

Solution:

QUESTION: 3

A simply supported beam carries a total load W which is uniformly distributed on the entire span. The center of beam is propped so that it is brought to the level of end supports. The prop reaction would be

Solution:

After equating central deflection for both the cases, we have 

QUESTION: 4

A point load placed at the mid span of a simply supported beam has been replaced by a uniformly distributed load of same total value. The central deflection in the later case will be

Solution:

For central point load P,

For udl of same total value,
