A W24 x 55 (ix = 1350 in) has been selected for a 21-ft simple span to support a total service live load of 3 k/ft (including beam weight). Is the center line deflection of this section satisfactory for the service live load if the maximum permissible value is 1/360 of the span?
Please show the breakdown of how you derive at your answer.
