Using Table 22.1, evaluate whether the stresses at the center of the span and the end of the span comply with the
permissible stress limits. The beam is classified as U-class.
Provide justifications for each condition listed in the table.
Note: Calculated stresses are to be taken from the above diagram, and permissible stresses are to be calculated
using Table 22.1.
