(A) The maximum permissible point laod at-mid-span may be obtained from the formula
P = 1/2 x U x Swhere
;
P = Maximum permissible point load in lbs, at mid-span
U = Maximum permissible uniformly distributed load in lbs, per foot run
S = the particular free span in feet
(B) In case of a span not listed above, the corresponding maximum permissible uniformly distributed load may be found from the formula :
U
= 4 x (U at 2 ft. span) / S2
(C)
Free span exceeding 16 ft. are not recommended
