Serviceability deflection limits are set according to a beam: Question 7Select one:a.Elastic modulusb.2nd moment of areac.spand.load
Solution
The serviceability deflection limits of a beam are set according to the span of the beam. This is because the deflection of a beam is directly proportional to the cube of its length (or span). Therefore, the longer the beam, the more it will deflect under the same load. This is why we need to limit the deflection for longer beams to ensure they remain serviceable. So, the correct answer is c. span.
